DISCUSSION
ISSUED AT 248 PM CDT THU APR 30 2026
A WEAK MESO LOW IN NORTHWEST FLOW WILL PUSH ACROSS THE STATE
THROUGH THIS EVENING BRINGING SOME CLOUD COVER AND A FEW
ISOLATED SHOWERS. DRY AND MORE CLEAR CONDITIONS WILL BE FOUND
IN THE WEST. SOME BREEZY NORTHWEST WINDS, COMBINED WITH LOW
AFTERNOON HUMIDITY VALUES COULD ALSO BRING SOME ISOLATED NEAR
CRITICAL FIRE WEATHER CONDITIONS THIS AFTERNOON AND EARLY
EVENING, MAINLY IN THE SOUTHWEST. TONIGHT, WINDS WILL BECOME
LIGHT AND VARIABLE WITH A SURFACE HIGH MOVING INTO THE REGION. A
WEAK MID LEVEL WAVE COULD BRING SOME CLOUDS AND PERHAPS A FEW
SPRINKLES OR FLURRIES OVERNIGHT TONIGHT INTO FRIDAY MORNING.
LOWS TONIGHT WILL GENERALLY BE NEAR 30 DEGREES. SURFACE HIGH
MOVES MORE INTO THE STATE ON FRIDAY, BRINGING LIGHT WINDS AND
MAINLY DRY CONDITIONS. WESTERLY WINDS ALOFT WILL BEGIN A
WARMING TREND WITH 60S IN THE WEST AND 50S IN THE EAST. THIS
WILL BRING SOME LOWER RH VALUES IN THE AFTERNOON ALTHOUGH LIGHT
WINDS WILL LIMIT THE FIRE DANGER THREAT. MILD AND CONTINUED DRY
CONDITIONS WILL THEN BE FOUND FRIDAY NIGHT, WITH LOWS IN THE 30S
TO LOWER 40S.
A SURFACE LOW IS FORECAST TO MOVE THROUGH SATURDAY, BRINGING
WARM TEMPERATURES IN THE 60S TO LOWER 70S. THIS COULD BRING SOME
INCREASED NORTHWEST WINDS AS WELL. DRY CONDITIONS SHOULD LIMIT
CHANCES FOR SHOWERS. THESE DRY CONDITIONS COMBINED WITH SOME
BREEZY WINDS COULD BRING SOME INCREASED FIRE WEATHER CONCERNS TO
PERHAPS NEAR CRITICAL FIRE WEATHER CONDITIONS. DRY CONDITIONS
WITH MILD TEMPERATURES THEN LOOK TO REMAIN FOR SATURDAY NIGHT.
SUNDAY LOOKS TO REMAIN ABOVE NORMAL TEMPERATURES, WITH CONTINUED
DRY AND BREEZY CONDITIONS. THIS AGAIN COULD BRING SOME INCREASED
FIRE WEATHER CONCERNS. SUNDAY NIGHT THROUGH MONDAY, A MAINLY DRY
COLD FRONT IS FORECAST TO PUSH THROUGH, BRINGING SLIGHTLY
COOLER TEMPERATURES. BREEZY TO WINDY CONDITIONS ARE POSSIBLE.
THIS COMBINED WITH CONTINUED LOW RH VALUES COULD LEAD TO SOME
NEAR CRITICAL FIRE WEATHER CONDITIONS ON MONDAY. CLUSTERS THEN
INDICATE NORTHWEST FLOW TO PREVAIL THROUGH AT LEAST MID NEXT
WEEK. THIS PATTERN IS EXPECTED TO BRING BELOW NORMAL
TEMPERATURES, BREEZY CONDITIONS, AND PERHAPS SOME ISOLATED TO
SCATTERED SHOWERS. TEMPERATURE SPREADS BEGIN TO BROADEN LATER IN
THE WEEK AS THERE REMAINS SOME UNCERTAINTY ON HOW FAR INLAND
THE NEXT RIDGE CAN BUILD. PERHAPS A SLIGHT WARMUP IS POSSIBLE
LATER NEXT WEEK WHILE LIMITED CHANCES FOR PRECIPITATION REMAIN.
