ISSUED AT 1047 PM CDT TUE OCT 20 2026
DRY NORTHWESTERLY TO NORTHERLY FLOW ALOFT PERSISTS THROUGH
THURSDAY, BETWEEN RIDGING OVER THE SOUTHERN PLAINS AND TROUGHING
ALONG THE EAST COAST. AT THE SURFACE, HIGH PRESSURE OVER THE
EASTERN CONUS MAINTAINS A DRY CONTINENTAL AIR MASS, WHILE A
SURFACE LOW MOVES SLOWLY NORTHEASTWARD OFF OF THE MID-ATLANTIC/NORTHEAST
COASTLINES. COOL NIGHTS AND TEMPERATURES NEAR TO SLIGHTLY ABOVE
AVERAGE ARE EXPECTED WITH NO RAIN. FRIDAY THROUGH THE WEEKEND THE
LOW PRESSURE SYSTEM OVER THE WESTERN ATLANTIC EXITS, WHILE A
CUTOFF LOW FORMS NEAR CUBA. THIS ALLOWS THE MID-LEVEL SUBTROPICAL
RIDGE TO BUILD EASTWARD, BUT A STRENGTHENING CAD WEDGE IN THE WAKE
OF THE ATLANTIC SYSTEM RESULTS IN SLIGHTLY COOLER HIGH
TEMPERATURES FOR THE WEEKEND. A SHORTWAVE TROUGH APPROACHES THE
AREA NEXT WEEK, BUT LITTLE TO NO MOISTURE RETURN IS INDICATED AT
THIS TIME AS HIGH PRESSURE PERSISTS AT THE SURFACE.
