REMAINDER OF THE WEEKEND: COLD SURFACE HIGH PRESSURE WILL HAVE
THE GREATEST INFLUENCE ON WEATHER FOR THE LOWER MS VALLEY REGION
THIS WEEKEND. DRY AND SEASONABLY COLD CONDITIONS (~5 TO 10 F BELOW
NORMAL) WITH FREEZING OVERNIGHT TEMPERATURES CAN BE EXPECTED.
MONDAY THROUGH CHRISTMAS EVE: DRY WEATHER WILL CONTINUE, BUT
EXPECT TEMPERATURES TO MODERATE SIGNIFICANTLY WITH THE UPPER LEVEL
FLOW BECOMING MORE ZONAL AND PACIFIC IN ORIGIN WHILE SURFACE WINDS
BECOME MORE SOUTHEASTERLY.
CHRISTMAS DAY THROUGH THE END OF THE WEEK: A SERIES OF MID
LATITUDE SHORTWAVE TROUGHS WILL TRAVERSE THE NATION AND IMPACT THE
FORECAST AREA. AS THE SURFACE WARM SECTOR INCREASES WITH EACH
APPROACHING TROUGH, IT IS POSSIBLE THAT SEVERE WEATHER MAY BECOME
A CONCERN, ESPECIALLY AS WE GO INTO FRI/SAT, SO BE SURE TO MONITOR
FOR UPDATES. /EC/
