UPPER LOW. EXPECT PLENTY OF CLOUDS IN THE NORTHERN 1/3 OF THE

STRATO CUMULUS. TEMPS WON/T RISE OUT OF THE 50S IN THE NORTH...AND
AROUND 60 IN THE SOUTH.

FOR TONIGHT...IT SHOULD CLEAR AND TEMPS SHOULD FALL INTO THE
MID/UPPER 30S. THERE COULD BE SOME FROST FOR SURE...BUT FOR NOW
WILL LEAVE OUT WITH A FEW CLOUDS AROUND. IF IT CLEARS OUT
TOTALLY...THE MORE WIDESPREAD FROST COULD BECOME A CONCERN AND
WILL MONITOR POTENTIAL.

ON MONDAY...WARMER AIR AND WESTERLY SFC FLOW WILL MOVE INTO THE
REGION. THIS WILL BOOST TEMPS FROM SUNDAYS READINGS...WITH LOW TO
MID 60S WEST AND NEAR 60 EAST WITH PLENTIFUL SUNSHINE.

MAINLY CLEAR SKIES. HIGHS ON TUESDAY SHOULD CONTINUE TO WARM AS

HAVE BEEN CONSISTENT WITH NW FLOW ALOFT TRANSITIONING THURSDAY TO
MORE ZONAL FLOW AND BY FRIDAY SOUTHWEST FLOW. AS A RESULT
TEMPERATURES WILL REACH INTO THE LOW 70S FOR HIGHS WITH INCREASING
MOISTURE AND INSTABILITY AS UPPER RIDGING INDUCES 850MB SOUTHERLY
