Area forecast discussion, Apr 1, 3:24 AM CDT, 5 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
324 AM CDT WED APR 1 2015

.DISCUSSION...
MOISTURE WILL REMAIN IN PLACE ACROSS THE AREA TODAY WITH A
DISTURBANCE MOVING FROM SOUTHWEST TX UP THROUGH THE ARKLATEX
REGION BY THIS AFTN. WILL KEEP A MENTION OF OF PRECIP ACROSS THE
SOUTHEAST. HOWEVER... IT WILL BE FARTHER WEST WHERE THERE WILL BE
SOME POTENTIAL TO SEE SOME STRONGER STORMS. BY THIS AFTN WE EXPECT
TO SEE A DRYLINE TAKE SHAPE ACROSS FAR WESTERN OKLAHOMA OR EASTERN
TEXAS PANHANDLE AS ANOTHER DISTURBANCE MOVES OUT OF COLORADO INTO
THE CENTRAL PLAINS. ALTHOUGH BEST FORCING AND MOST OF THE ACTIVITY
WILL REMAIN TO OUR NORTH... AN ISOLATED STORM OR TWO MAY BE ABLE
TO OVERCOME DESCENT CAPPING INVERSION AS FAR SOUTH AS NORTHWEST
OKLAHOMA. ANOTHER CONCERN FOR THIS AREA WILL BE FIRE WEATHER. VERY
WARM AND WINDY CONDITIONS WILL EXIST. THE MAIN QUESTION IS JUST
HOW FAR EAST WILL THE DRYLINE PUSH INTO THE AREA. WILL UPGRADE TO
RED FLAG WARNING AS USUALLY MODELS UNDERESTIMATE WIND SPEEDS A BIT
IN THE DEEPER MIXED AIRMASS TO THE WEST OF THE DRYLINE AND THEY
DON'T DROP DEWPOINTS ENOUGH.

ANOTHER ROUND OF STORMS EXPECTED BY THURSDAY AFTN AS A RATHER
STRONG COLD FRONT PUSHES SOUTH THROUGH THE AREA. A FEW OF THESE
STORMS COULD BE SEVERE. BEST CHANCE WILL BE EAST OF I-35. COOLER
AND DRIER AIR WILL OVERSPREAD THE AREA FOR FRIDAY INTO THE FIRST
PART OF THE WEEKEND. NEXT CHANCE FOR PRECIP WILL OCCUR EASTER
SUNDAY AS A DISTURBANCE MOVES NORTH OUT OF TX TO GO ALONG WITH
WAA. ANOTHER COLD FRONT EXPECTED NEXT TUESDAY.
