BRINGING SOME CHANCES FOR RAIN AND SNOW SHOWERS. SURFACE HIGH
THEN TAKES OVER FOR TONIGHT, HELPING TO CLEAR SKIES AND BRING
LIGHT WINDS. DRY CONDITIONS IN PLACE COMBINED WITH INCREASING
WINDS AT NIGHT SHOULD LIMIT FOG FORMATION TONIGHT. LOWS TONIGHT
ARE FORECAST IN THE 20S, WITH SOME TEENS IN THE NORTH. EXITING
HIGH THEN BRINGS A STEADY SOUTHERLY WIND ON MONDAY, AND WARMS
TEMPERATURES BACK INTO THE 40S AND 50S FOR MOST AREAS. THERE
COULD BE A FEW ISOLATED RAIN SHOWERS IN THE EAST ALONG A WEAK
WARM FRONT MONDAY AFTERNOON AND EVENING. A WEAK BACKDOOR COLD
FRONT THEN LOOKS TO MOVE THROUGH MONDAY NIGHT, KEEPING OVERNIGHT

WARMER SIDE OF THE FRONT IN THE SOUTHWEST. GENERALLY DRY
CONDITIONS ARE ALSO EXPECTED FOR TUESDAY. AS A SURFACE LOW TAKES
SHAPE TUESDAY NIGHT, A FRONTAL BOUNDARY MAY SET UP IN THE NORTH
BRINGING CHANCES FOR MAINLY SNOW. LOWS ALONG THIS BOUNDARY WILL
REMAIN IN THE TEENS AND 20S, WITH 30S IN THE SOUTH AWAY FROM
THIS BOUNDARY.

AND SNOW WILL BE FOUND IN THE NORTH ALONG THIS STALLED BOUNDARY,
WHILE OTHER AREAS SEE DRY AND BREEZY CONDITIONS WITH HIGHS IN
THE 50S AND 60S. ECMWF EFI NOT SHOWING MUCH OF A STRONG WIND
SIGNAL AT THIS TIME FOR WEDNESDAY. IF THIS CHANGES AND MIN RH
