.DISCUSSION...
SHOWERS WILL EXPAND IN COVERAGE ACROSS NORTH TEXAS THIS MORNING.
THE BEST ISENTROPIC LIFT WILL BE CONFINED TO THE EASTERN SECTIONS
OF NORTH TEXAS SO WILL KEEP THE HIGHEST POPS THERE. FURTHER
WEST...MOISTURE WILL BE ABUNDANT BUT LIFT WILL BE LIMITED SO ONLY
VERY LIGHT RAIN OR DRIZZLE IS EXPECTED. RAIN CHANCES SHOULD END
FROM WEST TO EAST THIS AFTERNOON WITH THE PASSAGE OF THE UPPER
TROUGH AXIS AND INCREASING LARGE SCALE SUBSIDENCE. CLOUDS WILL
ALSO BEGIN TO CLEAR FROM WEST TO EAST LATE THIS AFTERNOON/THIS
EVENING.
THE LOW LEVELS OF THE ATMOSPHERE WILL REMAIN NEARLY SATURATED
TONIGHT WITH A LIGHT WIND AND A DAMP/COOL GROUND. THEREFORE...
AREAS OF FOG SHOULD DEVELOP...ESPECIALLY ACROSS THE EASTERN
ZONES. THE FOG SHOULD BURN OFF SHORTLY AFTER SUNRISE SUNDAY AS
DRYER AIR MOVES IN FROM THE WEST.
SUNDAY WILL BE SUNNY AND WARM DAY WITH WEAK RIDGING ALOFT AND
SOUTH TO SOUTHWEST LOW LEVEL FLOW. HOWEVER...CLOUDS WILL BE ON THE
INCREASE SUNDAY NIGHT THROUGH MONDAY AHEAD OF AN APPROACHING UPPER
TROUGH AND ASSOCIATED COLD FRONT. EXPECT A FEW SHOWERS TO DEVELOP
IN THE EAST MONDAY AS LARGE SCALE LIFT INCREASES. THE RAIN CHANCES
WILL CONTINUE IN THE EAST MONDAY NIGHT AS THE COLD FRONT MOVES
ACROSS THE REGION. THE UPPER TROUGH AXIS WILL MOVE EAST OF THE
REGION TUESDAY AND DRIER AIR WILL FILTER INTO THE REGION.
GULF MOISTURE WILL REMAIN CUT OFF FROM NORTH TEXAS THE REMAINDER OF
THE WEEK AND ANOTHER PASSING UPPER TROUGH EXPECTED THURSDAY WILL HAVE NO
AVAILABLE MOISTURE TO PRODUCE ANY PRECIPITATION.
WARMER TEMPERATURES ARE EXPECTED TODAY THROUGH MONDAY WITH THE
WARMEST DAY BEING SUNDAY. COOLER AIR BEHIND THE COLD FRONT EXPECTED
MONDAY NIGHT WILL KNOCK TEMPERATURES BACK CLOSER TO SEASONAL
NORMALS THE REMAINDER OF THE WEEK. THE MEX NUMBERS STILL APPEAR
TOO WARM TUESDAY THROUGH FRIDAY SO WILL KEEP AFTERNOON HIGHS
GENERALLY IN THE 50S.
