Morning e-mail from Jeff:
Widespread severe weather outbreak likely today over the MS valley into east-central TX.
Usually warm air mass has spread very far northward for late January with 600am temperature of 59 degrees at Chicago. In fact the low so far this morning at BUSH IAH has been 72 which is about 10 degrees above our normal daytime high! With such a warm air mass over much of the nation east of the Rockies and a powerful storm system edging into the plains state, severe weather is likely. Locally southerly winds have remained gusty overnight and this continues to help break up or at least mitigate widespread sea fog conditions along the coast even though dewpoints are well above nearshore water temperatures. Have seen a better fetch of “chilled” wind over the extreme SE TX/SW LA coast where sea fog bank has maintained better definition over the past 24 hours. Will continue to deal with the sea fog threat for the next 12 hours or prior to the arrival of a fast moving cold front this evening.
Next item is the severe weather threat and chances for thunderstorms with the cold front this evening. Main dynamics and strongest lift will be focused NE of the region over AR where SPC moderate risk outline is in place. Best moisture is overhead now and will steadily shift eastward during the day well before the lift and slightly cooling arrive aloft. With afternoon surface temperatures likely filtering with 90 or better over NE MX in the slightly higher terrain and increasing SW winds in the mid level transporting this warm nose over the region…the dreaded cap looks to increase through the day. Highs in the upper 70’s will not be enough to break through the warm layer aloft especially given the deck of stratus. However some slight cooling of the mid levels may be possible as the trough axis approaches and combines with strong surface convergence with the cold front. While SPC slight risk takes in about the NE ½ of the region, feel the severe threat will be limited to the Lake Livingston area where capping is weakest and tail end of stronger dynamics aloft reside. Main threat in this area will be damaging winds to 60mph. For the rest of the area a broken band of showers and possibly a thunderstorm will be possible and this is supported by the TEXAS TECH meso model showing a thin line of showers/storms with the front. Think capping will hold strong over the southern and southwestern parts of the area keeping thunder out of the picture.
Front will quickly sweep offshore this evening with temperatures Wednesday morning 25 degrees cooler than today. Little weather is expected for the rest of the week into the weekend with lows in the 40’s and highs in the 60’s to near 70 under mostly sunny skies.

...THERE IS A SLGT RISK OF SVR TSTMS SURROUNDING THE MDT RISK...FROM
ERN TX/OK TO THE LOWER MS VALLEY AND OH VALLEY...
...ERN OK/TX TO THE MS AND OH VALLEYS THROUGH TONIGHT...
A LARGE-SCALE MID-UPPER TROUGH OVER THE HIGH PLAINS WILL PROGRESS
EWD OVER THE LOWER PLAINS TO THE MS VALLEY BY EARLY WEDNESDAY.
WITHIN THE LARGE TROUGH...A PRIMARY SHORTWAVE TROUGH OVER THE SRN
HIGH PLAINS...WITH AN ASSOCIATED 100 KT MIDLEVEL JET...WILL EJECT
ENEWD TOWARD ERN OK/NW AR/MO OVERNIGHT. LIKEWISE...AN ASSOCIATED
SURFACE CYCLONE NOW IN N CENTRAL OK WILL DEEPEN AND MOVE NEWD ACROSS
MO/IL TO LOWER MI...ALONG A PRE-EXISTING BAROCLINIC ZONE.
MEANWHILE...A BROAD MOIST SECTOR IS ALREADY ESTABLISHED FROM ERN
TX/OK TO THE LOWER AND MID MS VALLEY REGION...WHERE BOUNDARY LAYER
DEWPOINTS RANGE FROM THE UPPER 60S ALONG THE NW GULF COAST...TO
56-60 F FARTHER N INTO MO/IL. ADDITIONAL EWD EXPANSION OF THE MOIST
SECTOR IS LIKELY THROUGH TONIGHT ACROSS THE MS/TN AND LOWER OH
VALLEY REGION...IN RESPONSE TO THE DEEPEN CYCLONE AND A
STRENGTHENING SLY LLJ.
WIDESPREAD CONVECTION IS ONGOING ALONG AND JUST AHEAD OF THE SURFACE
COLD FRONT FROM CENTRAL OK TO NRN MO. THOUGH EXTENSIVE CLOUDS ARE
PRESENT THROUGH MUCH OF THE WARM SECTOR...CONTINUED MOISTURE
ADVECTION FROM THE S AND MODEST SURFACE HEATING IN CLOUD BREAKS WILL
BOOST MLCAPE VALUES TO THE 1000-2000 J/KG RANGE ACROSS E TX AND SE
OK THIS AFTERNOON...WITH LESSER BUOYANCY FARTHER TO THE E AND NE.
THERE ARE ALREADY INDICATIONS THAT ADDITIONAL PRE-FRONTAL CONVECTION
WILL DEVELOP FROM NE TX INTO SE OK/WRN AR AND EVENTUALLY SRN MO THIS
AFTERNOON ALONG THE MOIST AXIS. VERTICAL SHEAR PROFILES WILL BE
FAVORABLE FOR SUPERCELLS WITH AN ATTENDANT RISK FOR TORNADOES AND
DAMAGING WINDS ACROSS THIS CORRIDOR. FARTHER N...CONVECTION WILL
GRADUALLY EVOLVE INTO A WELL-DEVELOPED QLCS WITH AN INCREASING RISK
FOR DAMAGING WINDS LATER THIS AFTERNOON INTO EARLY TONIGHT...WITH A
RISK OF EMBEDDED MESOVORTICES AND TORNADOES.
THE GREATEST SEVERE RISK IS EXPECTED THIS EVENING THROUGH
TONIGHT...BEGINNING AS THE PRE-FRONTAL CONVECTION NEAR AND NW OF THE
ARKLATEX...AND CONTINUING OVERNIGHT AS ADDITIONAL PRE-FRONTAL
CONVECTION FORMS WITHIN ONE OR MORE WARM SECTOR CONFLUENCE BANDS
NEAR THE MS RIVER. VERTICAL SHEAR WILL BE EXTREMELY STRONG WITHIN A
MOIST ENVIRONMENT WITH AT LEAST WEAK SURFACE-BASED INSTABILITY.
THOUGH MLCAPE MAY ONLY REACH 500-750 J/KG...EFFECTIVE SRH OF 500-700
M2/S2 IN ASSOCIATION WITH A 70-80 KT LLJ WILL SUPPORT THE POTENTIAL
FOR A FEW STRONG TORNADOES WITH FAST-MOVING PRE-FRONTAL
SUPERCELLS...AS WELL AS CIRCULATIONS EMBEDDED WITHIN WHAT WILL
BECOME A WELL-FORMED SQUALL LINE. WIDESPREAD AND SIGNIFICANT
DAMAGING WINDS WILL ALSO BE POSSIBLE AS FAR NE AS THE LOWER OH

Another frontal passage in Austin ... another frontal passage in Austin with no rain as we watch it glide to our north and northeast. 
Lake Travis will be only a mud puddle by August.

Looks like the line just exploded along/just east of I-35 as the front passed. Now you know how I have felt most of the last two years.

Yeah Jason ... based on what I'm seeing on radar now and the lightning out my office window to the northeast ... that's exactly what has happened.jasons wrote:Looks like the line just exploded along/just east of I-35 as the front passed. Now you know how I have felt most of the last two years.
Hey, Portastorm... how did you enjoy that 85 degree weather today? Goodness. I was out on campus and just couldn't believe my eyes when I pulled up the temp on my phone and the temp was that high. Unbelievable. I feel you though in the rain department. Was hoping to get some rain, but ...nothing.
At least we'll have some cooler weather tomorrow.

Cap held as expected...not sure why SPC keeps dropping that slgiht risk area so far back SW when the inversion is so strong....maybe for the isolated cell that can break through and go severe. This is not 2012...that is for sure!Ed Mahmoud wrote:That was depressing. About a tenth at local airports.

Though we did not go Severe across most of S.E. Texas, there was a very healthy line of storms, and moderate to heavy rain for some. Porter, Montgomery County, got a very nice period of heavy rainfall last night.
