DISCUSSION
(THIS AFTERNOON THROUGH TUESDAY)
ISSUED AT 110 PM CST WED FEB 11 2026
THROUGH FRIDAY:
THE COLD FRONT IS BEGINNING TO REACH THE I-20 CORRIDOR WITH
TEMPERATURES DROPPING INTO THE 50S BEHIND IT. SINCE THE SHORTWAVE
HAS PUSHED EAST OF THE AREA, ONLY A BROKEN LINE OF LIGHT SHOWERS
IS LOCATED ALONG IT. THE FRONT AND ASSOCIATED SHOWERS WILL DROP
SOUTHWARD THROUGH THE AFTERNOON. CAMS INDICATE POTENTIAL FOR SOME
ISOLATED TO WIDELY SCATTERED MODERATE SHOWERS TO DEVELOP ALONG A
PRE-FRONTAL TROUGH WHERE SOME WEAK INSTABILITY WILL BE PRESENT.
EQUILIBRIUM LEVELS ARE RIGHT AROUND -10C, SO THE CHANCES FOR ANY
SHOWERS TO PRODUCE LIGHTNING ARE LESS THAN 10 PERCENT AT ANY GIVEN
LOCATION. DRY AIR ADVECTION AND LIGHT NORTHERLY WINDS WILL RESULT
IN COOLER TEMPERATURES OVERNIGHT, GETTING DOWN WITHIN A COUPLE
DEGREES OF FREEZING IN OUR FAR NORTHERN COUNTIES. DRY NORTHWEST
FLOW ALOFT WILL BE IN PLACE THURSDAY AND FRIDAY, WITH OCCASIONAL
MAINLY HIGH CLOUDS AT TIMES. THE FRONT WILL REMAIN STALLED TO OUR
SOUTH. PLEASANT CONDITIONS ARE EXPECTED WITH TEMPERATURES STILL A
LITTLE BELOW NORMAL. WILL NOTE FIRE DANGER WILL BE A BIT ELEVATED
GIVEN THE VERY DRY AIR MASS, THOUGH LIGHT WINDS WILL PREVENT RISK
OF ANY RAPID SPREAD/RED FLAG CONCERNS.
SATURDAY/SUNDAY:
THE NEXT SOUTHERN STREAM SHORTWAVE IS CURRENTLY NEAR CALIFORNIA,
AND WILL MOVE EASTWARD ACROSS THE SOUTHERN CONUS THIS WEEKEND
ALONG WITH AN ASSOCIATED SURFACE LOW. SOME SHOWERS MAY DEVELOP BY
SATURDAY AFTERNOON, BUT THE OVERALL TREND IS DRIER. OVERALL
BEGINNING TO SEE BETTER AGREEMENT BETWEEN ENSEMBLE CLUSTERS ON THE
SYNOPTIC FEATURES, WITH TYPICAL AMOUNTS OF UNCERTAINTY ON THE
MESOSCALE DETAILS. IN GENERAL A LARGE AREA OF RAIN/POTENTIALLY A
QLCS WILL MOVE IN LATE SATURDAY NIGHT/EARLY SUNDAY MORNING, MOVING
QUICKLY EASTWARD ACROSS THE STATE BY MIDDAY. AS IS TYPICAL SHEAR
IS PLENTIFUL BUT INSTABILITY IS VERY QUESTIONABLE. THE WARM FRONT
AND ASSOCIATED LOWER 60S DEW POINTS WILL BE ATTEMPTING TO LIFT
NORTHWARD AS THE QLCS MOVES IN. USUALLY THE MOST LIKELY SCENARIO
IN THESE CASES IS THAT THE CONVECTION OUTRUNS THE SURFACE-BASED
INSTABILITY, AS DEPICTED BY THE MAJORITY OF THE GUIDANCE. THIS
WOULD ESPECIALLY BE THE CASE IF CONVECTION DEVELOPS ALONG THE
COAST GIVEN THE LOWER LATITUDE OF THE SHORTWAVE, DISRUPTING THE
NORTHWARD ADVECTION OF INSTABILITY. ULTIMATELY IT'S TOO EARLY TO
KNOW FOR SURE IF JUST ENOUGH INSTABILITY CAN BUILD IN AHEAD OF THE
LINE (ON THE ORDER OF A COUPLE HUNDRED J/KG OF CAPE) FOR ANY
MARGINAL SEVERE THREAT TO DEVELOP IN OUR FAR SOUTHERN COUNTIES,
BUT THE OVERALL THREAT IS LOW AT THIS TIME. WILL ALSO NOTE THAT
GUIDANCE DOES SHOW MORE INSTABILITY DEVELOPING BEHIND THE LINE
WITH THE UPPER LOW. IT'S ALWAYS IMPORTANT TO NOT JUST LOOK AT
CAPE PLOTS IN THIS SITUATION, BUT TO ALSO LOOK AT WHERE THE
CONVECTION IS RELATIVE TO THE CAPE. THOUGH IF THERE IS SUFFICIENT
MOISTURE, THEN SOME THUNDERSTORMS COULD DEVELOP BY AFTERNOON WITH
A LOW THREAT OF SMALL HAIL. WHILE MINOR FLOODING OF POOR DRAINAGE
COULD OCCUR, THE SYSTEM SHOULD BE PROGRESSIVE ENOUGH TO PREVENT
WIDESPREAD FLOODING.
BEHIND THE SYSTEM, ABOVE NORMAL TO WELL ABOVE NORMAL TEMPERATURES
ARE EXPECTED NEXT WEEK.
