COLDER AIR ARRIVES THIS EVENING AS SURFACE HIGH PRESSURE BUILDS SOUTH

BECOME BREEZY TO WINDY EARLY TONIGHT...BUT SHOULD BEGIN TO DIMINISH
LATER TONIGHT AS THE SURFACE HIGH SETTLES DOWN INTO THE AREA. THE
SURFACE RIDGE WILL MOVE EAST OUT OF THE PANHANDLES BY TUESDAY EVENING
AND TUESDAY NIGHT IN RESPONSE TO DEVELOPING SURFACE LOW PRESSURE
ALONG THE LEE OF THE ROCKIES. WINDS WILL BECOME SOUTHERLY TO
SOUTHWESTERLY BY WEDNESDAY AND THURSDAY AND WILL INCREASE INTO THE
BREEZY TO WINDY CRITERIA AS THE SURFACE TROUGH DEEPENS. AN UPPER
RIDGE ALSO BUILDS IN OVER THE PANHANDLES BY THE MIDDLE OF THE WEEK
AND THEN SHIFTS EASTWARD BY FRIDAY AS A CLOSED UPPER LOW DIGS JUST
OFF THE COAST OF SOUTHERN CALIFORNIA AND THEN TRACKS EASTWARD INTO
THE SOUTHWESTERN STATES BY SATURDAY. A SURFACE LOW OVER SOUTHEASTERN
COLORADO AND POSSIBLE PSUEDO-DRYLINE INTO THE EASTERN PLAINS OF NEW
MEXICO SATURDAY COULD SET THE STAGE FOR CONVECTIVE DEVELOPMENT
BEGINNING AS EARLY AS FRIDAY NIGHT...BUT BETTER CHANCES BY SATURDAY
AFTERNOON AS THE MAIN SHORTWAVE APPROACHES FROM THE WEST AND
INSTABILITY INCREASES. SOME STRONG TO POSSIBLY SEVERE THUNDERSTORMS
LIKELY SATURDAY AFTERNOON AND EVENING ACROSS MOST OF THE PANHANDLES.

PRESSURE GRADIENT WILL TIGHTEN AS THE SURFACE TROUGH DEEPENS ALLOWING
FOR THE WINDS TO INCREASE TO AROUND 15 TO 25 MPH WITH HIGHER GUSTS
AND MINIMUM AFTERNOON RELATIVE HUMIDITIES FALL TO AROUND 15 TO 20
PERCENT BOTH DAYS. POSSIBLE ELEVATED TO NEAR CRITICAL FIRE WEATHER
