.LONG-TERM (SUNDAY THROUGH FRIDAY)...REINFORCING SURFACE ANTICYCLONE
BUILDS ACROSS THE REGION SUNDAY THEN MOVES OFFSHORE MONDAY WITH A
WARMER SOUTHWEST FLOW RESUMING. CLOUDINESS IS EXPECTED TO BE SPARCE
DURING THIS TIME. NO SIGNIFICANT DEPARTURES FROM MOS TEMPERATURE
GUIDANCE SUNDAY BUT WENT AT OR BELOW SUNDAY NIGHT AS LOWER
TROPOSPHERIC WINDS REMAIN SUFFICIENTLY LIGHT. POINT SOUNDINGS EVEN
SUGGEST SOME SHALLOW PATCHY FOG BUT NOT SIGNIFICANT ENOUGH TO
INCLUDE. DEVIATIONS FROM MOS TEMPERATURES MONDAY/MONDAY NIGHT WERE
ALSO INSIGNIFICANT.
COMPRESSIONAL HEATING ASSOCIATED WITH A SOUTHWEST SURFACE FLOW WILL
RESULT IN UNSEASONABLE WARMTH TUESDAY AND PORTIONS OF THE CWA
WEDNESDAY. ARCTIC AIRMASS(-40F) ENSCONCED OVER CANADA WILL SPLINTER
AND HEAD SOUTHWARD WEDNESDAY. THE WINDSHIFT LINE WILL LIKELY
PROGRESS ACROSS THE REGION WEDNESDAY AFTERNOON WITH THE ARCTIC AIR
GRADUALLY BLEEDING INTO THE AREA THEREAFTER. THURSDAY WILL BE A
TRANSITIONAL DAY THEN A 500HPA SHORTWAVE WILL INTERACT WITH A
COASTAL TROUGH THURSDAY NIGHT/FRIDAY WITH CLOUDINESS BECOMING MORE
PROMINENT. ISENTROPIC UPGLIDE BECOMES MORE FAVORABLE BUT
CONDENSATION PRESSURE DEFICITS ONLY LOWER SUFFICIENTLY FROM THE
IMMEDIATE COAST EASTWARD. WILL THEREFORE GRADE POPS FROM SLIGHT
CHANCE WEST TO CHANCE EAST. LATEST GFS POINT SOUNDINGS SUGGEST THE
POSSIBILITY OF FROZEN PRECIPITATION BUT STRENGTH/DEPTH OF ARCTIC
AIRMASS UNCERTAIN GIVEN THAT IT IS DAY 7. ONLY SLIGHT MODIFICATIONS
WERE APPLIED TO THE PREVIOUS TEMPERATURE GRIDS.
I like the second to the last line. I know it's travel time for Christmas, but the possiblity for some sort of frozen precip would be fun.
