Damaging freeze hits the Midwest U.S.

Large portions of the Midwest U.S. shivered through a hard freeze (temperatures below 28°F ) this morning, and freezing temperatures extended as far south as Tennessee and North Carolina. Though the cold temperatures were not unusual for this time of year, they likely caused widespread damage to flowering plants fooled into blooming by last month's unprecedented "Summer in March" heat wave. Growers of apples, pears, peaches, nectarines, plums, and cherries worked during the night and early morning to minimize the damage by running large fans and propane heaters in their orchards, and some even rented helicopters in an attempts to keep temperatures a few degrees warmer. While freezing temperatures for an extended period will not kill the trees, they will destroy the flowers and fragile buds that are needed to produce fruit later in the year. Temperatures of approximately 28°F will kill about 10% of fruit tree buds and flowers, while temperatures of 25°F will produce a 90% kill rate. Temperatures of 25° were common over Michigan, Wisconsin, and Minnesota this morning, and I expect that this morning's freeze was severe and widespread enough to cause tens of millions of dollars in damage to the fruit industry. There have been numerous freezes and frosts over the Midwest's fruit growing regions since late March, and orchards are definitely taking a major beating from the weather. It will be several weeks before the extent of the damage is known, but I think that so far it is unlikely that the industry has suffered a billion-dollar disaster, such as occurred in 2007. A warm spell in March that year was followed by cold temperatures in early April that were 10 - 20 degrees below average, bringing killing frosts and freezes to the Midwest and South that caused $2.2 billion in agricultural damage, wiping out apple, peach, winter wheat and alfalfa crops.

History of billion-dollar U.S. freezes
Freezes can cause big damage to agriculture. According to NOAA's National Climatic Data Center, there have been six billion-dollar U.S. freezes since 1980, accounting for 5% of all billion-dollar weather-related disasters. Five of these freezes affected California or Florida; one hit the Midwest. Ranked by damages (in 2011 dollars), here are the six billion-dollar U.S. freeze events since 1980:

1) California Freeze of December 1990. Severe freeze in the Central and Southern San Joaquin Valley caused the loss of citrus, avocado trees, and other crops in many areas. Several days of subfreezing temperatures occurred, with some valley locations in the teens. $5.9 billion in direct and indirect economic losses, including damage to public buildings, utilities, crops, and residences.

2) Florida Freeze of December 1983. Severe freeze central/northern Florida; about $4.5 billion damage to citrus industry.

3) California Freeze of December 1998. A severe freeze damaged fruit and vegetable crops in the Central and Southern San Joaquin Valley. Extended intervals of sub 27° F temperatures occurred over an 8-day period; $3.5 billion estimated damages/costs.

4) Florida Freeze of January 1985. Severe freeze in central/northern Florida; about $2.5 billion damage to citrus industry.

5) East/Midwest freeze of April 2007. Widespread severe freeze over much of the East and Midwest (AL, AR, GA, IL, IN, IA, KS, KY, MS, MO, NE, NC, OH, OK, SC, TN, VA, WV), causing significant losses in fruit crops, field crops (especially wheat), and the ornamental industry. Temperatures in the teens/20's accompanied by rather high winds nullified typical crop-protection systems. Over $2.2 billion in damage/costs.

6) California Freeze of January 2007. For nearly two weeks in January, overnight temperatures over a good portion of California dipped into the 20's, destroying numerous agricultural crops, with citrus, berry, and vegetable crops most affected. $1.5 billion estimated in damage/costs; 1 fatality reported.

Record warmth in the Western U.S.
As is often the case when one part of the country is experiencing much cooler than average temperatures, the other half is seeing record warmth, due to a large bend in the jet stream that allows warm air to flow northwards. Much of Wyoming, Montana, Idaho, and Colorado experienced record warm temperatures yesterday. Most notably, Jackson, Wyoming hit 72°F, the earliest 70° reading in their history, and 27° above their normal high of 45°.


Figure 2. Severe weather risk for Saturday, April 14, 2012, from NOAA's Storm Prediction Center.

Tornado outbreak possible Saturday in Kansas and Oklahoma
A significant tornado outbreak is possible on Saturday, says NOAA's Storm Prediction Center. A warm, unstable airmass will collide with cold air funneling down from Canada, and strong jet stream winds will create plenty of wind shear. There is the potential for long-track strong tornadoes over Oklahoma and Kansas on Saturday, and SPC has has issued their second highest level of alert, a "Moderate Risk," for the region.

First named storm in the Atlantic possible next week
Both the GFS and ECMWF models are predicting that an extratropical "cut-off" low will separate from the jet stream early next week several hundred miles east of Bermuda, and linger for several days over subtropical waters with temperatures in the 22 - 24°C range. These ocean temperatures may be warm enough to allow the storm to organize into a named subtropical storm. However, climatology argues against such an occurrence; there has been only one named April storm in the Atlantic since 1851. If a subtropical storm does form next week, it would probably not affect any land areas.

Alberto now? I don't have my hopes up, but it's looking as if this will resemble the February blob where models agreed and we actually got something in the area. It might not develop, but the idea and situation probably will.

I just don't think it's going to happen... What do you think its chances are?

Typically I think hte same way, but with some vigorous model agreement. And the nature, I think its a reasonable possibility. I give it a 55% chance of occuring.

To add to Cybrted's point, here's the Euro 12Z Run.
seems to be just getting stronger and stronger on each run.
Euro brings it down to a 994 MB storm. and if rang true would be:
Sub-tropical Storm Alberto
50-60 Mph Storm

Very interesting setup going on here, similar to Ana in 2003. If we do get an April storm, it will not signal an active hurricane season because we're still pretty much in a La Nina phase at the moment.

Anyways here's my model rundown, the latest model run of the ECMWF continues to show a sub-tropical storm, and a large one too and pretty powerful, by 120 hours (Tuesday), the 12z GFS also has it, but weaker, in the same timeframe. The NOGAPS has it by Tuesday, and the CMC has one but much smaller and surrounded by multiple lows, putting in question if it's a cyclone on there.

To summarize, there is a moderate chance that a sub-tropical storm will develop next week. The general consensus is that this tropical cyclone will have a massive pressure gradient, which confirms its nature as a sub-tropical cyclone. The genesis appears similar to Ana 2003 and Sean 2011, and would be the 2nd named storm in the month of April in recorded history.

Bad news means the market sky rockets!


Actually, bad news has been causing the markets to slump. Investors are worried about the recovery stalling out or at least slowing down.

When jobs are plentiful a rise in unemployment can mean that businesses will be able to hire for less money and increase profits. Under those conditions a rise in unemployment can cause markets to rise. We aren't in that situation now.

The "unemployed" count has been going up largely because a number of people who had dropped out of looking for jobs have been feeling a bit more optimistic and are back out looking.

The most reliable measurement of how we're doing along those lines is net jobs created. For the first quarter it looks pretty good. The March numbers were a bit surprising until folks realized that unusual warm weather in late winter started up a lot of jobs that would be expected to start in March.

What is the footage showing?


It's a flow of hail stones and meltwater in a stream (probably normally a dry creek bed).

Notice how it behaves almost in a plastic way, a lot like a volcanic lahar. It is almost "plastic", not quite solid and yet not quite fluid. You can see it has uprooted at least one live tree and some other plants, and transporting some very large objects.

this alert from the "wired news" homepage..................Eyes are still on Nevado del Ruiz in Colombia, where the volcano has been showing increasing signs of an impending eruption over the last month. Last week, the Colombian Geological Survey (INGEOMINAS) Manizalez Volcano Observatory placed the volcano on Orange Alert status, which means they expect an eruption in days to weeks. Over the weekend, there was some confusing news about whether the volcano was moved to Red Alert status (eruption in 24-48 hours), however, it looks like Ruiz was moved to Red Alert by the Colombian Meteorological Office (IDEAM) based on the threat of potential lahar generation. However, INGEOMINAS has kept the volcanic alert status at Orange. This is one of the ways that disseminating public information about the state of activity at a volcano can be problematic – if multiple government agencies can declare different alerts with the same color/number scheme, then confusion can easily arise about what the threat might be.
Excerpt..An explosive eruption from Ruiz's summit crater on November 13, 1985, at 9:08 p.m. generated an eruption column and sent a series of pyroclastic flows and surges across the volcano's broad ice-covered summit. Pumice and meltwater produced by the hot pyroclastic flows and surges swept into gullies and channels on the slopes of Ruiz as a series of small lahars. Flowing downstream from Ruiz at an average speed of 60 km per hour, lahars eroded soil, loose rock debris and stripped vegetation from river channels. By incorporating water and debris from along river channels, the lahars grew in size as they moved away from the volcano--some lahars increased up to 4 times their initial volumes.

Within four hours of the beginning of the eruption, lahars had traveled 100 km and left behind a wake of destruction: more than 23,000 people killed, about 5,000 injured, and more than 5,000 homes destroyed along the Chinchiná, Gualí, and Lagunillas rivers. Hardest hit was the town of Armero at the mouth of the Río Lagunillas canyon, which was located in the center of this photograph. Three quarters of its 28,700 inhabitants perished.

More people sought unemployment benefits last week, pushing the number of applicants to the highest level in two months.

The Labor Department said Thursday that weekly unemployment benefit applications jumped 13,000 to a seasonally adjusted 380,000. The previous week's figures were also revised higher. The four-week average, a less volatile measure, rose to 368,500.


Greater hiring hasn't led to larger paychecks. Wages aren't rising fast enough to keep up with inflation. Rising gas prices are also weighing on consumers' ability to spend money on other goods and services. Europe's debt crisis has flared up again, as Spain and Italy have been forced in recent days to pay higher interest rates on their debts.

The Labor Department said Thursday that weekly unemployment benefit applications jumped 13,000 to a seasonally adjusted 380,000. The previous week's figures were also revised higher. The four-week average, a less volatile measure, rose to 368,500.


Greater hiring hasn't led to larger paychecks. Wages aren't rising fast enough to keep up with inflation. Rising gas prices are also weighing on consumers' ability to spend money on other goods and services. Europe's debt crisis has flared up again, as Spain and Italy have been forced in recent days to pay higher interest rates on their debts.
