April in January: spring-like severe weather and record warmth in the Midwest

The calendar says its January, but the atmosphere looks more like April over the Midwest U.S., where a spring-like surge of warm air is interacting with a strong low pressure system to create a dangerous severe weather situation. The warm air surging northwards has already broken high temperature records for the date in Chicago, where the mercury hit 61°F at 7 am CST; a tornado watch is posted for portions of Texas, Oklahoma, Kansas, and Arkansas. Golf-ball sized hail fell at three locations in Oklahoma already this morning, and a wind gust of 75 mph was reported in a thunderstorm near Omega, Oklahoma. NOAA's Storm Prediction Center has placed portions of Arkansas, Louisiana, Texas, Tennessee, Missouri, Alabama, Oklahoma, Illinois, Indiana, and Mississippi in their "Moderate Risk" region for severe weather on Tuesday. This is the first "Moderate Risk" forecast issued during 2013. The primary threat will be damaging thunderstorm winds, but we will also see tornadoes, with the potential for a few strong EF-2 and EF-3 twisters. The surge of warm moving northwards ahead of the cold front spawning today's severe weather is bringing in warmth unprecedented for January in some locations. Monday was the hottest January day on record in Topeka, Kansas, which hit 77°F. That's 36°F above average. and 3° warmer than their previous highest January temperature. Columbia, Missouri tied its all-time warmest January temperature, 77°. Kansas City (74°F) and Wichita (74°F) both fell 1° short of tying their all-time January hottest temperature records. Balloon soundings of the atmosphere taken last night showed moisture levels in the top 5% for a January day over much of the Midwest, and several stations may set all-time rainiest January day records today. One candidate is Flint Michigan, where a heavy thunderstorm moved in at 7:30 am, dumping 0.75" of rain. With another round of thunderstorms expected tonight, Flint is poised to break its record for rainiest January day in its history--the 1.34" that fell on January 18, 1949.


Figure 1. A crazy weather day for the U.S.: our severe weather map from 10 am EST Tuesday, January 29. Severe thunderstorms were occurring in Kansas and Oklahoma, flood watches were posted for Illinois, Michigan, Indiana, Ohio, and Wisconsin, and winter weather advisories, high wind advisories, and fire weather advisories were posted in other locations.


Figure 2. NOAA's Storm Prediction Center has placed portions of Arkansas, Louisiana, Texas, Tennessee, Missouri, Alabama, Oklahoma, Illinois, Indiana, and Mississippi in their "Moderate Risk" region for severe weather on Tuesday. This is the first "Moderate Risk" forecast issued during 2013.

Chicago's wild January weather ride continues
Chicago's craziest January in memory got even stranger today, when a surge of warm air pushed the temperature to 61°F at 7 am, breaking the previous high temperature record of 59°F for the date. Spring-like thunderstorms, accompanied by temperatures in the mid-60s are expected this afternoon--just a week after the city recorded a high temperature of 11°F and a low of -1°F (on January 22nd.) Chicago has been above 65°F in January just once in its history--on January 25, 1950, when the mercury hit 67°F. The average January high in the Windy City is 30°F, and today will be the 4th day the city has been 20 or more degrees warmer than that during January 2013. The roller coaster goes back downhill after the cold front moves through early on Wednesday, though--Chicago's high on Friday is expected to be near 15°F, with a morning low around 5°F. Chicago has also experienced record low snowfall this winter; the city got it's first 1-inch snowstorm of the season on Friday, when 1.1" fell at O'Hare Airport. This was the latest first 1-inch snow in city history, and ended a 335-day streak without a 1-inch snowstorm, the longest such streak since records began in 1872. Chicago has managed just 2.9" of snow during the winter of 2012 - 2013, which is 16" below average.

Chicago's roller coaster of temperatures doesn't compare, though, to what happened in Nowata, Oklahoma during the period February 10 - 17, 2011. A cold air mass combined with a fresh snow pack and calm winds allowed Nowata to hit a low of -31°F on February 10, 2011--the all-time coldest temperature ever recorded in Oklahoma. Gradual warming accelerated over the next week, and temperatures peaked at a record high of 79 degrees on February 17. According to the National Weather Service in Tulsa, Okla., this 110-degree temperature rise was the greatest change within seven days in Oklahoma history.


Video 1. In this video done by Peter Sinclair for the Yale Forum on Climate Change, I offer my thoughts on the roller coaster ride of temperatures in Michigan this winter, look back at the remarkable weather of 2012, and discuss what 2013 might bring. My main concern: drought.

ISOLATED SIGNIFICANT tornadoes is better than "signficant long tracking tornadoes." Hopefully we won't see that kind of wording for a while...:)

Big drop in StL & Spfld, IL temps since last checked before I left work, 68 & 64 then, both show 57 now. I'm still in mid 60s, hasn't quite made it here yet. Winds have picked up a little and some rain. Has crossed I-55, so getting close.

I don't think they'll go with PDS. I'd say it'll be about as high end as a non-PDS watch can be though. Not seeing a lot of discrete supercells at this point.

Ok, I'm in Northwest Arkansas, and I drove through a damage path about a 100 yards wide this evening. It's along the path for the cell that went East of Fayetteville Arkansas, up into Southern Mo where a new tornado warning was issued later. That cell showed a weak couplet at a location on radar approximating the damage. The damage was mostly to trees, but pretty discrete along that path.Guess we will see if it gets classified as a tornado or not. Looks to me like it was, but I don't get to make those calls.

Current; 30/01/2013 08:00 8.97m(29.42ft)


Focus shifts to recovery as floodwaters recede

Australian Defence Force personnel are waiting to enter the flooded Queensland city of Bundaberg, as the search continues for two men missing in the state's floodwaters.

But as the floods recede, Brisbane residents have been warned some suburbs could run out of drinking water after mud-laden water knocked out out one of the city's treatment plants.



The key points from the flood crisis this morning:


Residents across Queensland's south-east are waiting for the waters to recede after yesterday's peaks.
ADF relief teams are on stand-by to help the clean-up in Bundaberg.
Bundaberg's floodwaters peaked yesterday at 9.53m.
Two men are thought to be missing in floodwaters near Gatton, west of Brisbane.
Brisbane's Lord Mayor says there is still a concern that parts of greater Brisbane could run out of water.
Residents of Maclean and Harwood Island in northern New South Wales were evacuated ahead of an expected flood peak early this morning.
But New South Wales communities have avoided the worst of the floods.

0437 PM CST TUE JAN 29 2013

AREAS AFFECTED...LOWER MS VALLEY

CONCERNING...SEVERE POTENTIAL...TORNADO WATCH LIKELY

VALID 292237Z - 300100Z

PROBABILITY OF WATCH ISSUANCE...80 PERCENT

SUMMARY...PRE-FRONTAL CONVECTION ALONG THE SABINE RIVER TO CNTRL LA
SHOULD EVOLVE INTO DISCRETE SUPERCELLS AS ACTIVITY APPROACHES THE
LOWER MS VALLEY. TORNADOES /POSSIBLY SIGNIFICANT/ AND DAMAGING WINDS
WILL BE THE PRIMARY THREATS.

DISCUSSION...AN AREA OF WARM SECTOR SHOWERS WITH A FEW EMBEDDED
TSTMS ALONG THE SABINE RIVER INTO CNTRL LA SHOULD GRADUALLY DEEPEN
THROUGH THE EVENING HOURS FED BY UPSTREAM PW VALUES OF 1.5 INCHES.
AS LARGE-SCALE ASCENT AND LOW TO DEEP-LAYER SHEAR ALL FAVORABLY
INCREASE...DISCRETE SUPERCELLS SHOULD DEVELOP. SOME
CONVECTION-ALLOWING MODEL GUIDANCE INDICATES THIS
OCCURRING...ALTHOUGH APPEARING LIKELY TOO SLOW /BETWEEN 03-06Z/. IT
APPEARS MORE PROBABLE BASED ON OBSERVATIONS THAT SUPERCELLS WILL
OCCUR BY THE 00-03Z TIME FRAME...WITH THE PRIMARY THREATS BEING
TORNADOES /POTENTIALLY SIGNIFICANT/ AND DAMAGING WINDS.
