Torrential rains in Oklahoma; Summer in March continues for Midwest
A significant flood event is underway in Eastern Oklahoma, where widespread rainfall amounts of 3 to 5 inches have fallen since yesterday. Up to four more inches of rain is likely today, and the National Weather Service in Tulsa is warning of the potential for "widespread and potentially catastrophic areal flooding and river flooding" should some of the higher rainfall amounts being forecast materialize. Numerous main-stem rivers across eastern Oklahoma and northwest Arkansas are now approaching flood stage, and will likely experience moderate to major flooding into Wednesday. Rainfall has also been heavy over Eastern Texas, with widespread amounts of 2 - 4 inches. These heavy rains are causing some street flooding, but in general, will be a benefit, as moderate to severe drought conditions still cover most of the region.
Figure 1. Radar-estimated rainfall for Eastern Oklahoma since March 19, 2012, as estimated by the Tulsa, Oklahoma radar.
The storm system responsible is a massive, slow-moving trough of low pressure over the Western U.S. that is colliding with the warmest and moistest air mass ever recorded in March in the Central and Eastern U.S. According to the NWS in Minneapolis, Minnesota, moisture flowing northwards into Minnesota along the cold front early this week had the highest levels of moisture ever recorded so early in the year. At the boundary between the Western U.S. trough of low pressure and Central U.S. ridge of high pressure, a cold front is lifting huge quantities of moisture-laden air aloft, forcing torrential rains to fall. The cold front is also expected to trigger a Slight Risk of severe weather over East Texas, Western Louisiana, and Southern Arkansas today, says NOAA's Storm Prediction Center. Severe thunderstorm watches are already posted for much of East Texas, as seen on our Severe Weather Map. Three tornadoes were reported yesterday in Texas, and eleven touched down the previous day in Oklahoma, Nebraska, and South Dakota. The tornado that hit North Platte, Nebraska two days ago was rated a strong EF-3, and injured four people.

Summer in March continues for the Midwest
The ongoing March heat wave in the Midwest will continue to set all-time heat records through Thursday, gradually shifting its peak intensity eastwards during the week. A few highlights from yesterday's records:
Pellston, Michigan in the Northern Lower Peninsula is called "Michigan's Icebox", since it frequently records the coldest temperatures in the state, and in the entire nation. But the past three days, Pellston has topped out at 80° - 82°F, the first 80°F March days in their history. Yesterday's 82° reading broke the previous record for the date (56° in 1976) by an amazing 26°, and was 44°F above average. Nearby Traverse City hit 83°F yesterday, the third consecutive day the city has experienced its hottest March temperature on record.
International Falls, Minnesota hit 78°F yesterday, 42° above average, and the 2nd hottest March temperature on record in the Nation's Icebox. The record of 79°F was set the previous day. Remarkably, the low temperature for International Falls bottomed out at 60°F yesterday, tying the previous record high for the date. I've never seen a station with a century-long data record have its low temperature for the date match the previous record high for the date. Yesterday was the seventh consecutive day that International Falls broke or tied a daily record. That is spectacularly hard to do for a station with a century-long weather record. The longest string of consecutive records being broken I'm aware of is nine days in a row, set June 2 - 10, 1911 in Tulsa, Oklahoma (with weather records going back to 1905.) International Falls has a good chance of surpassing nine consecutive records this week.
Record heat in Canada
Record-breaking heat has also penetrated into the Prairie provinces of Canada over the past week. Winnipeg, Manitoba has broken its record high for the past five days in a row, and hit 24°C (75.2°F) yesterday, its hottest March temperature on record. Forecast high temperatures for Wednesday and Thursday across Ontario are near 26°C, which will threaten the records for hottest March day in history for Windsor, London, Hamilton, and Toronto.
Figure 3. The jet stream pattern features a large, southwards dipping bulge over the Western U.S., creating a trough of low pressure with cold and snow, and a large, northwards looping bulge over the Central U.S., creating a record-strength ridge of high pressure.
Why the record early-season warmth?
The unusual warmth is due to a loop in the jet stream that has created a large upper-level ridge of high pressure that is stuck in place over the Eastern U.S.--a phenomenon known as a "blocking pattern." Since the jet stream acts as the boundary between cold air to the north and warm air to the south, and the large loop in the jet places its axis far to the north of the eastern U.S., summer-like warmth has developed over the eastern half of the U.S. Conversely, colder than average temperatures have developed over the western third of the U.S. behind the southwards-dipping loop of the jet stream. This jet stream pattern is too extreme to be stable, and the big loop over the Western U.S. will break off and form a giant eddy on Wednesday. The resulting area of low pressure will be known as a "cut-off low", because it will be cut off from the jet stream. The cut-off low will drift slowly eastwards during the week, gradually bringing an end to "Summer in March" over the Eastern half of the U.S.

DEVELOP A SIMILAR OUTCOME ACROSS THE WEST BY ALLOWING THE LARGE

VERY DIFFERENT WAYS. THE ECMWF ALLOWS A PERTURBATION TO ENTER THE

BY THE CANADIAN AND A LACK OF MODEL AGREEMENT SUPPORT REJECTING
THE CANADIAN SOLUTION AT THIS TIME...WITH THE REMAINING CLUSTER OF
SOLUTIONS SUFFICIENTLY NARROW IN SPREAD TO WARRANT A GFS/ECMWF
COMPROMISE THROUGH THE END OF THE PERIOD.

Looks like the radar was heavily affected by bright banding based on rainfall reports from Muskogee, which is very near that radar max. While lots of rain has fallen, there is a big difference between over 15 inches and not even five inches of rain.
Muskogee, Davis Field
It's kinda crazy that in the span of about 100-200 miles the Ocean temperature differs by about 6-8 degrees Celsius down in the Eastern Pacific towards Central America towards 10 degrees North.
Anywhere from 40 - 20 degree North and west of 70 West (Gulf of Mex and Carolina coast down to Miami and the Bahamas) Those areas are all above normal. Then it gets even more interesting towards NYC. 3 degree Celsius. Storms are going to be able to sustain their strengths much further north if these trends continue.
Then you can see where the African dust storms are really doing a number on the SST around the Cape Verde s...
Several years ago climate scientists started telling us that a warming climate would likely mean more periods of drought and more periods of very heavy precipitation (all that extra water evaporated into the atmosphere).
Joe Romm wrote a book called "Hell and High Water" in 2006.
Perhaps the only thing that we should be surprised about is how soon and how intensely those predictions seem to be making us a visit.
Can we use past weather patterns to predict tomorrow's weather? The overall system has changed and that makes yesterday's observations less valuable.
A pettern change is coming for sure. A pattern that will bring some of the coldest air to the northern US since FEBRUARY! Also a return to stormy wx for the SE US.
So....what have i missed(un-intentionally)
Only several years ago? Many of these types of events were suggested even decades earlier than present, albeit with lower amounts of scientific confidence. Even around the time of Romm's book, the media-publicized opinions and even those accepted by the world governments for inclusion in the IPCC assessment reports were more conservative than the general opinion of climate scientists.
Hell I'd take a 1/2 inch at this point.

At the moment, major flooding is forecast for two areas. The hydrographs below should update as time goes on.
Antlers, Oklahoma
Erie, Kansas
How much rain did you get RitaEvac? Looks like a solid 1" to 2".
Something like that, will find out when I get home and check the gauge
Me too (and several others according to twitter and chrome). Almost ten hours without WU. I wondered whether the server had been flooded. Nice to have you all back.
:-)
Looks like another slug of storms will wrap into Houston later especially on the eastside of Houston.
I had a problem earlier getting in but then logged out and went right back in and I was fine.
The big drought in West Africa continues as I see. That means the Tropical Wave train that emerge the African Coast will be less than normal,and of those that can survive the dust, they will wait to develop closer to the islands with the below sst's going on in the MDR.
What do you and RitaEvac think about this?
Link
Seems feasable.
No other models are following that from what I can see. I just can't see more rounds of precipitation developing like that with this colder air filtering in behind this boundary... I would be ecstatic if that did happen though
They're talking about another round coming across from the west around the ULL later tonight, but atmosphere has been worked over pretty well, unless the sun starts coming out late today maybe something will pop, out in the hill country
