NATIONAL WEATHER SERVICE LOUISVILLE KY
921 AM EDT FRI MAR 13 2026
FORECAST IS BASED ON IGNITION TIME OF 1000 EDT ON MARCH 14.
IF CONDITIONS BECOME UNREPRESENTATIVE...CONTACT THE NATIONAL WEATHER
SERVICE.
..WIND ADVISORY IN EFFECT UNTIL 8 PM EDT THIS EVENING
DISCUSSION
A STRONG LOW PRESSURE SYSTEM WILL PASS WELL TO THE NORTH OF
THE AREA TODAY, WITH A TRAILING COLD FRONT APPROACHING THE REGION THIS
AFTERNOON AND EVENING. NO PRECIPITATION IS EXPECTED WITH THIS SYSTEM;
HOWEVER, STRONG SOUTHWEST WINDS ARE EXPECTED TODAY, WITH WIDESPREAD
30 TO 40 MPH WIND GUSTS AND SCATTERED 40 TO 50 MPH GUSTS LIKELY THROUGH
THIS AFTERNOON. IT IS LESS CERTAIN THAT RH VALUES WILL DROP LIKE THEY
DID YESTERDAY AFTERNOON AS THERE WILL BE MORE CLOUD COVER AND LESS DRY
AIR ALOFT TO MIX DOWN TO THE SURFACE. STILL, ANY SOUTH OR WEST ASPECTS
WHICH SEE BREAKS IN THE MID-LEVEL CLOUDS COULD SEE RH VALUES FALL INTO THE
20S. OTHERWISE, GIVEN THE STRONG WINDS AND FAIRLY DEEP MIXING DEPTHS,
DISPERSION PARAMETERS ARE EXPECTED TO BE IN THE EXCELLENT RANGE TODAY.
DRY WEATHER SHOULD CONTINUE INTO SATURDAY, WITH MUCH WEAKER WINDS AND
SHALLOWER MIXING HEIGHTS EXPECTED TOMORROW.
