FNT IS ENTERING NW CWA ATTM AND AS IT DOES...WND SHUD PICK UP AND BE
GUSTY OUT OF NW TODAY. CAA BEHIND THIS S/W WL KEEP TEMPS FM WARMING
TOO MUCH TODAY. IN FACT...WL PBLY SEE PLENTY OF CLOUD COVER ACRS CWA
THIS MORN WITH SOME CLEARING THIS AFTN FAR W AND FAR S ALLOWING
TEMPS TO WARM INTO LOWER 40S THERE WITH 30S ELSEWHERE. CUD ALSO SEE
A FEW FLURRIES THIS AFTN NERN CWA AND WL KEEP IN FCST. LOOKS LIKE IT
WL BE SLOWER TO CLEAR OUT ERN CWA TONIGHT WITH STRATUS HANGING
PRETTY TOUGH THRU MOST OF NITE. THIS SHUD HOLD TEMPS UP ACRS ERN CWA
EVEN WITH CAA. SFC HIGH WL SETTLE OVR ERN DAKOTAS ON THU AND WITH
LACK OF SNOW COVER MOST PLACES...EVEN WITH NWLY FLOW...WILL PBLY MIX

EXPECTED.

MODELS CONT TO INDICATE THAT SYS FOR FRI WL REMAIN S OF CWA. AM
ALWAYS LEERY ABOUT SRN STREAM WAVES AS THEY TEND TO LIFT A LTL
FURTHER N THAN FCST. SO ALTHOUGH MODELS KEEP PRECIP S OF CWA
FRI...CAN NOT RULE OUT COMPLETELY THAT SOME SNOW MAY CLIP FAR SERN
CWA. DEFINITELY COLD ENUF THAT PRECIP WOULD BE SNOW IF IT DOES
OCCUR. SO WL CONT TO 30 TO 50% POPS ACRS FAR SERN CWA ON FRI. THIS
SYS SHUD QUICKLY EXIT BY FRI EVE WITH GENLY NW FLOW ALOFT KEEPING
TEMPS CLOSE TO NORM FRI THRU SUN. LACK OF SNOW COVER IN MANY PLACES
WL ALLOW COLDER AIR TO MODIFY A BIT.

WEAK SFC BNDRY WILL STRADDLE FAR SRN CWA SAT NITE THRU SUN
SEPERATING COLDER AIR TO N FROM MILDER AIR TO THE S. SOME PAC
MOISTURE WL SLIDE SE ACRS CWA N OF THIS FNT AND CUD PRODUCE LTL
LIGHT SNOW LATE SAT NITE AND SUN. NOT MUCH FORCING AND LOW LEVEL
REMAIN FAIRLY DRY SO WL ONLY HAVE SMALL POPS. CUD BE MORE OF A
