tacoman25 Posted May 1, 2013 Share Posted May 1, 2013 Amarillo may have a 50-degree drop from 5PM yesterday to 5PM today...97 to 47? It's currently 50. They may drop into the upper 20s by tomorrow morning. The 97 they saw yesterday was the third warmest April temp on record for them. And they have a legitimate shot at their all-time record cold May temp tomorrow night. Unreal. Link to comment Share on other sites More sharing options...

Jonbo Posted May 2, 2013 Share Posted May 2, 2013 Switched from moderate/heavy rain to sleet and then moderate/heavy snow pretty quickly in West DSM abount 5:30-6am. Been coming down steadily at least still moderate/heavy snow. Accumulating on grassy surfaces and roads starting to. Absolutely mind boggling it's going to snow all day (in May!) with 3-5" and locally higher amounts here by tomorrow morning. Link to comment Share on other sites More sharing options...
Stebo Posted May 3, 2013 Share Posted May 3, 2013 Completely incredible how far the expanse of freeze warnings are in Texas tonight, I bet there will be several record lows for the month of May tonight all over the Southern Plains. Interestingly enough though, some of the record lows for today were set in 2011, just goes to show you how easily things can switch further down the line.

on_wx Posted May 7, 2013 Share Posted May 7, 2013 MODELS ARE SHOWING THE POTENTIAL FOR SOME DECENT SURFACE BASED INSTABILITY DEVELOPING BY WEDNESDAY AFTERNOON. HOWEVER WITH THE WEAK MID LEVEL FLOW...DEEP LAYER SHEAR IS ONLY PROGGED TO BE 20 TO 30 KTS. ADDITIONALLY MODELS ARE SUGGESTING A NOCTURNAL MCS COULD MOVE ACROSS NORTHEAST KS EARLY WEDNESDAY...WHICH BRINGS INTO QUESTION WHETHER THE ATMOSPHERE WILL RECOVER AND WHERE THE BEST INSTABILITY WILL FORM. THERE COULD BE SOME STRONG STORMS WITH HAIL AND WINDS...BUT AM NOT SURE THE SHEAR PROFILE WILL BE CONDUCIVE FOR PERSISTENT SUPERCELL STORMS. MOST OF THE MODEL SOLUTIONS SEEM TO POINT TO WEDNESDAY NIGHT AS THE BEST OPPORTUNITY FOR WIDESPREAD PRECIP AS POSSIBLE SHORTWAVE ENERGY MOVES ACROSS THE INVERTED TROUGH AXIS EXPECTED TO BE ACROSS THE FORECAST AREA. THEREFORE HAVE THE HIGHEST POPS FOR WEDNESDAY NIGHT. From TOP. Link to comment Share on other sites More sharing options...

Srain Posted May 8, 2013 Share Posted May 8, 2013 It does appear that severe storms will begin to develop across potions of Central Texas and translate E over the next couple of days. While the best chance for large hail and damaging winds associated with those severe storms appear to be near the Austin/San Antonio area, we will need to monitor just where the outflow boundaries set up over the next several days as moisture increases off the Gulf and moves inland setting the stage for a potential heavy rainfall event due to training storms from the Middle Texas Coast on E into Louisiana through Saturday.

andyhb Posted May 8, 2013 Share Posted May 8, 2013 Parameters should be increasing later on as the LLJ intensifies, some pretty nice looking hodographs being indicated across Western OK and the Eastern TX Panhandle towards Lawton and SPS later on. The second svr tstm watch issued did mention a possible upgrade to a tornado watch later on should conditions warrant it. Link to comment Share on other sites More sharing options...
