DISCUSSION
ISSUED AT 145 PM CDT TUE APR 28 2026
THE CIRRUS VEIL HAS PARTED FROM EARLIER THUNDERSTORMS UP WIND, WITH
MORE SUNSHINE ON TAP FOR THE AFTERNOON. SO FAR, WE SEE A WIDE
RANGE OF TEMPERATURES HERE FROM 77 AT DEQUEEN TO 89 AT LUFKIN.
S/SW WINDS ARE GOING TO GUST UP A LITTLE AND THE CAP WILL ELEVATED
AND COOL IN THE PROCESS. OUR DEW POINTS REMAIN LOADED FOR BEAR
WITH LOWER 70S ON AVERAGE. IT'S 68 IN CENTER FOR THE DRIEST AND 75
FOR THE WETTEST. ALTHOUGH IDABEL IS 81 OVER 81 AND MAY BE STUCK.
THE GUSTY SW WINDS ARE FEEDING INTO THIS NEW (ROUND TWO) THUNDERSTORM
DEVELOPMENT OVER N TX, WEST OF LAKE TEXOMA. A LINE EXTENDS NE
ALONG THE FRONTAL BOUNDARY INTO OKLAHOMA CITY AND TULSA. SO PLENTY
OF OPPORTUNITY FOR DEVELOPMENT TO FILL IN AHEAD OF THAT BOUNDARY
IN TORNADO WATCH 171. WE WILL LIKELY SEE A NEW WATCH COORDINATED
LATER THIS AFTERNOON FOR OUR EVENING HOURS. THE EXPECTED
DEVELOPMENT WILL LIKELY BE LONG LIVED INTO THE NIGHT WITH THE COLD
FRONT FALLING IN BEHIND THE CONVECTIVE ASSIST. SO WE WILL STAND
BY WITH OUR SEAT BELTS FASTENED TONIGHT, AND BY THIS TIME
TOMORROW A 1018MB AIR MASS WILL POSITION ITSELF OVER MO/AR.
CLOUDS FROM NEW STORMS AHEAD OF THE E PACIFIC CUT-OFF LOW'S
APPROACH IN THE PATTERN WILL KEEP US FROM HEATING UP MUCH KEEPING
70S FOR A COUPLE OF DAYS. AND MORE HIGH PRESSURE TO COME AS OUR NE
WINDS ARE REINFORCED EARLY ON FRIDAY AHEAD IN CONJUNCTION WITH
OUR NEXT GOOD RAIN COMING. SO LOOK FOR 60S FOR HIGHS AT THAT TIME.
LOWS WILL BE COOLER IN THE 50S, AND LIKELY 40S FOR ONE DAY ON
SUNDAY MORNING THANKS TO THAT SECONDARY AIR MASS THIS WEEKEND.
THE WPC HAS US SLIGHT RISK FOR EXCESSIVE TODAY UNDER THE TOWERS
AND THEN AGAIN FRIDAY FOR THE SOAKER TO KICK OFF THE MAY BUCKET
RAINFALL ENTRIES. NOTHING MORE THAN MARGINAL RISK WISE LATER THIS
WEEK FROM THE SPC 4-8, BUT HAIL COULD BECOME A THREAT WITH THE
COLD CORE LOW OPENING UP INTO A WAVE, BUT TRACKING RIGHT OVER US
FRIDAY NIGHT. BEYOND A BEAUTIFUL WEEKEND, NEXT WEEK HAS A THIRD
AIR MASS LOOKING GOOD IN THE 10 DAY OUTLOOK. /24/
