NOT TOO MANY CHANGES THIS MORNING WITH THE WEATHER FORECAST. MILD
WEATHER THROUGH THIS WEEKEND BECOMING WARMER NEXT WEEK AS OUR WELL
EARNED THAW CONTINUES. A WEAK UPPER LOW WILL UNDERCUT TENNESSEE OVER
THE WEEKEND, WITH RAIN LIKELY TO HOLD OFF ON SATURDAY UNTIL LIGHT
RAIN CHANCES BEGIN SNEAKING IN SATURDAY NIGHT THANKS TO THE LEADING
ISENTROPIC LIFT AHEAD OF THE LOW. DRY LOW LEVEL AIR SHOULD HOLD RAIN
AT BAY, BUT ANYTHING THAT FALLS SATURDAY EVENING WOULD BE LIGHT. THE
VAST BULK OF THE RAIN WILL FALL ON SUNDAY, WITH A 50% CHANCE FOR
OVER AN INCH OF RAIN. LOOKING THROUGH THE VARIOUS DETERMINISTIC
GUIDANCE HAS DIFFERENT SWATHS OF AN INCH OF RAIN, NORTH VS SOUTH VS
WESTERN PORTIONS OF THE AREA. THIS IS THE BEST SHOT OF RAIN THROUGH
THE NEXT 7 DAYS, AND WITH SEVERE DROUGHT, IT IS VERY MUCH NEEDED.
NOT SEEING ANY SIGNIFICANT MOUNTAIN WIND FLOW, THOUGH THERE MAY BE
SOME BREEZY WINDS ON THE PLATEAU SATURDAY NIGHT INTO SUNDAY MORNING,
IN SPITE OF POOR MIXING.
ONCE THE LOW MOVES OUT VERY EARLY ON MONDAY, A DRY PATTERN SETS UP
WITH A WARMING AIRMASS THANKS TO HIGHER UPPER HEIGHTS SETTING UP
OVER THE BROADER MID SOUTH REGION. A COUPLE OF WEAK SYSTEMS TRAVERSE
THE EASTERN US OVER THE COURSE OF NEXT WEEK, BUT ONLY A WEAK CYCLONE
LATE WEEK NEXT WEEK CARRIES LOW RAIN CHANCES FOR US. OTHERWISE THE
WARMING TREND WILL BRING WIDESPREAD 60S AND 70S TUESDAY AND AFTER.
