A SHORT WAVE TROUGH IS EXITING TO OUR SOUTHEAST AND WE WILL SEE
SHORT WAVE RIDGING BUILD IN OVERNIGHT. THIS WILL BRING A CONCERN
FOR FOG, SOME OF THE FOG COULD BE DENSE WITH THE HIGHEST CHANCES
IN SOUTHERN AND WESTERN AREAS. A DENSE FOG ADVISORY MAY BE NEEDED
DEPENDING ON HOW WIDESPREAD THE FOG DEVELOPMENT IS.
A SHORT WAVE TROUGH EXITING THE GREAT LAKES WILL PUSH A BOUNDARY
SOUTH. THIS WILL PUSH INTO THE AREA OVERNIGHT AND WILL BRING SOME
CLOUD COVER AND A LOW SHOWER CHANCE BEFORE DAYBREAK TO THE
NORTHWEST PART OF THE AREA. THE BOUNDARY WILL SLOWLY WORK EAST
THROUGH THE REGION AS THE DAY GOES ON. CAPE WILL INCREASE TO ABOVE
1000 J/KG BY THE AFTERNOON WITH AROUND 20 KNOTS OF BULK SHEAR.
THE BOUNDARY WILL BE ENOUGH FORCING TO KICK OFF SOME SCATTERED
SHOWERS AND THUNDERSTORMS WITH THE HIGHEST CHANCES EAST OF I-65.
LAPSE RATES WILL BE POOR AND FORCING WITH THE BOUNDARY WILL ONLY
BE MARGINAL, THIS WILL KEEP THE SEVERE THREAT VERY LOW. HIGHS WILL
MAKE IT INTO THE UPPER 80S TO LOWER 90S.
SHOWERS AND THUNDERSTORMS WILL DIMINISH QUICKLY AFTER SUNSET AND
DRY WEATHER SETTLES IN THURSDAY NIGHT. PATCHY FOG WILL BE A
CONCERN ONCE AGAIN WITH THE HIGHEST CHANCES FOR FOR FOG OVER THE
PLATEAU. TROUGHING WILL PUSH TO OUR EAST ON FRIDAY AS THE FOUR
CORNERS RIDGE AMPLIFIES. THIS WILL BRING QUIET AND DRY WEATHER
