DISCUSSION...
TODAY STARTS A WEEK OF WEATHER EXTREMES FOR OKLAHOMA. TODAY AND
TUESDAY WILL BE EXTREMELY WARM. FOG MAY BE SLOW TO BURN OFF THIS
MORNING BECAUSE OF LIGHT WINDS AND THE REMNANT FROM ACROSS
CENTRAL OKLAHOMA. WINDS WILL INCREASE TUESDAY WHEN A SURFACE
PRESSURE TROUGH DEVELOPS OVER THE HIGH PLAINS. THIS WILL BRING
SOUTHWEST WINDS INTO WESTERN OKLAHOMA AND NEAR RECORD MAXIMUM
TEMPERATURES CLOSE TO 80 DEGREES. WINDS MAY BE SUFFICIENT TO CAUSE
RED FLAG CONDITIONS AND A FIRE WEATHER WATCH REMAINS EFFECTIVE
FROM WEST CENTRAL OKLAHOMA TO NORTH TEXAS TUESDAY AFTERNOON.
MEANWHILE, A COLD FRONT IS EXPECTED TO DROP TEMPERATURES INTO THE
40S BY LATE AFTERNOON IN NORTHWEST OKLAHOMA. COLDER AIR WILL MOVE
ACROSS OKLAHOMA WEDNESDAY AND DAYTIME TEMPERATURES IN THE 20S AND
30S ARE EXPECTED THURSDAY UNTIL SUNDAY. A BROAD UPPER TROUGH WILL
LIKELY SEND SEVERAL SHORT-WAVE TROUGHS ACROSS OKLAHOMA THURSDAY
AND FRIDAY WHEN PRECIPITATION IS LIKELY. FORECAST TEMPERATURE
PROFILES SUPPORT SNOW IN NORTHERN OKLAHOMA, FREEZING RAIN IN
SOUTHEAST OKLAHOMA AND SLEET AND COMBINATIONS IN-BETWEEN THESE
AREAS. SEE THE SPECIAL WEATHER STATEMENT FOR FURTHER DETAILS.
