DRY, COLD, ARCTIC AIR WILL CONTINUE SPILLING INTO THE AREA TODAY.
READINGS WILL START OUT IN THE 27-37F RANGE WILL STRUGGLE TO WARM
MUCH MORE THAN ABOUT 10 DEGREES THIS AFTERNOON DESPITE PLENTIFUL
SUNSHINE.
TONIGHT, MOSTLY CLEAR SKIES AND LIGHTER WINDS WILL ALLOW READINGS TO
FALL BELOW FREEZING FOR ALL BUT MAYBE THE BEACHES (WHO TOO WILL BE
CLOSE). IN GENERAL, AREAS NORTH OF I-10 HAVE A BETTER SHOT OF SEEING
HARD FREEZES...MEANING TEMPS AT OR BELOW 24F FOR 2+ HOURS. WILL LET
THE DAYSHIFT TAKE A LOOK AT ANOTHER ROUND OF MODEL DATA AND FINE
TUNE THINGS AND UPGRADE ALL, OR PORTIONS OF, THE ONGOING FREEZE
WATCH TO A WARNING IF NEED BE. REGARDLESS OF ANY WINTER RELATED
WARNING/ADVISORY HEADLINES...THE MESSAGING IS THE SAME - IT'S GOING
TO BE COLD AND WE ENCOURAGE FOLKS TO TAKE THE NECESSARY COLD WEATHER
PRECAUTIONS AND PREPARATIONS.
SURFACE HIGH PRESSURE SLOWLY TRACKS TO OUR EAST ON SUNDAY. WE SHOULD
SEE SOME MODERATING TEMPERATURES AND MOISTURE RETURN HEADING INTO
EARLY NEXT WEEK. MID-UPPER RIDGING EXPANDS ACROSS THE WESTERN CONUS
AND HEALTHY SSEWD SHORTWAVE DIVING DOWN THE PLAINS INTO TX DIGS OUT
ANOTHER EAST CONUS TROF BY MIDWEEK. THIS PATTERN WILL FAVOR OUR NEXT
TUE NIGHT OR WED MORNING FRONTAL PASSAGE LOCALLY. WE SHOULD SEE
PLENTY OF MOISTURE TO WORK WITH FOR SOME SHOWER AND ISOLATED TSTMS
TO DEVELOP AHEAD OF THIS BOUNDARY. SURFACE AND UPPER RIDGING IN ITS
WAKE WILL PROVIDE DRY, SEASONABLE WX IN ITS WAKE FOR THE REMAINDER
OF THE WORK WEEK. 47
