DISCUSSION
KEY MESSAGE 1: NEAR-RECORD WARMTH FOR ONE MORE DAY FRIDAY.
ANOMALOUSLY HOT TEMPERATURES CONTINUE ACROSS THE FORECAST AREA FOR
ONE MORE DAY TOMORROW BENEATH AN ANOMALOUSLY STRONG RIDGE AND AHEAD
OF A STRONG COLD FRONT THAT IS EXPECTED TO PUSH THROUGH THE AREA
FRIDAY NIGHT. NEAR RECORD HIGHS ARE EXPECTED IN THE AFTERNOON,
ESPECIALLY GIVEN COMPRESSIONAL HEATING AHEAD OF THE APPROACHING
FRONT. HIGHS IN THE UPPER 80S TO LOWER 90S ARE STILL EXPECTED. IF
YOU ENJOY THE HEAT, FRIDAY IS GOING TO BE YOUR LAST CHANCE FOR
SUMMER-LIKE TEMPERATURES FOR A WHILE. A SIGNIFICANT COOL-DOWN
IS ON THE WAY, AND WILL BE VERY NOTICEABLE.
KEY MESSAGE 2: A STRONG COLD FRONT IS FORECAST TO PUSH THROUGH
THE REGION FRIDAY NIGHT, USHERING IN COOLER WEATHER THIS
WEEKEND.
THE FORECAST REMAINS ON TRACK, WITH SOME NOTABLE WRENCHES THAT
ARE INCREASINGLY APPEARING IN GUIDANCE. GUIDANCE HAS SLOWED THE
FRONT DOWN SLIGHTLY ON FRIDAY NIGHT OVER THE LAST COUPLE OF
DAYS; EVEN STILL, IT IS FORECAST TO PASS THROUGH THE AREA
BETWEEN 10P FRIDAY AND 3A SATURDAY. COOLER AIR IS FORECAST TO
RUSH INTO THE AREA BEHIND IT, WITH STRONG GUSTY WINDS EXPECTED
AS WELL. THE TROUGH FORCING ALL OF THIS HAS TRENDED MUCH SHARPER
OVER THE LAST SEVERAL DAYS, WITH GUIDANCE NOW SHOWING SOME FORM
OF THE TROUGH CUTTING OFF TO OUR EAST BY SATURDAY NIGHT OR
SUNDAY. IT IS UNLIKELY, BUT THERE IS STILL A SMALL CLUSTER OF
ENSEMBLE GUIDANCE THAT IS TRYING TO CUT THE UPPER LOW OFF CLOSER
TO US, WHICH WOULD IMPACT OUR WEATHER MORE THAN EXPECTED. THE
PASSING BLOW OF LIGHT SHOWERS EXPECTED EARLY SATURDAY MORNING
WOULD LINGER LONGER IN THIS SCENARIO AND HAVE SOME DOWNSTREAM
IMPACTS WITH TEMPS. THIS IS AN UNLIKELY SCENARIO BUT DOES HAVE
SOME SUPPORT IN THE DETERMINISTIC GUIDANCE AS WELL. REGARDLESS,
SOME SHOWERS ARE LIKELY EARLY ON SATURDAY AS THE FRONT CLEARS,
MOISTURE LAGS A BIT BEHIND, AND INTENSE SYNOPTIC LIFT ALLOWS FOR
SOME RAIN TO DEVELOP. WINDS ARE FORECAST TO BE QUITE BREEZY ON
SATURDAY. BUFKIT TIME/HEIGHT PLOTS SUGGEST THAT WIND GUSTS OF
30-40 MPH ARE POSSIBLE DURING THE DAY AS A COOL AND DRY AIRMASS
RAPIDLY ADVECTS INTO THE AREA. WE WILL NEED A LAKE WIND ADVISORY
AND HONESTLY ARE BORDERING ON WIND ADVISORY CRITERIA. IF THE
COASTAL LOW DEVELOPS A BIT EARLIER AND CLOSER TO US THAN IS
CURRENTLY EXPECTED, WE DEFINITELY WILL NEED TO WATCH FOR
STRONGER GUSTS. SUNDAY WILL BE QUITE CHILLY WITH TEMPS IN THE
LOW 60S AND OVERNIGHT LOWS IN THE 40S. FROM THERE, A MODEST WARM
UP CLOSER TO NORMAL IS EXPECTED INTO NEXT WEEK. GIVEN PRESENCE
OF NORTHEASTERLY FLOW AND STRONG HIGH PRESSURE, COOL TEMPS AND
DRY AIR IS EXPECTED DEEP INTO NEXT WEEK.
AVIATION /00Z FRIDAY THROUGH TUESDAY/
MAINLY VFR CONDITIONS EXPECTED OUTSIDE OF POSSIBLE MORNING
STRATUS OR FOG ALONG THE COASTAL PLAIN.
CLEAR SKIES AND LIGHT AND VARIABLE OR CALM WINDS WILL CONTINUE
OVERNIGHT. SOME GUIDANCE HINTS AT POSSIBLE STRATUS/FOG
DEVELOPING ALONG THE COASTAL PLAIN IMPACTING OUR TYPICAL FOG-
PRONE SITES OF OGB AND AGS. CONFIDENCE REMAINS LIMITED BUT WENT
AHEAD AND ADDED A TEMPO GROUP FOR INTERMITTENT IFR VSBYS BETWEEN
7-12Z, SIMILAR TO LAST NIGHT. OTHERWISE, GENERALLY VFR
CONDITIONS THROUGH THE PERIOD. A STRONG COLD FRONT WILL APPROACH
THE REGION ON FRIDAY AND AN INCREASED PRESSURE GRADIENT WILL
RESULT IN SOUTHWESTERLY WINDS INCREASING TO AROUND 10 KNOTS
AFTER 15Z WITH SOME HIGHER GUSTS AROUND 17 KNOTS LIKELY BY
AFTERNOON. WINDS WILL SHIFT LATER FRIDAY NIGHT FROM THE
NORTHWEST BUT THAT IS EXPECTED TO HAPPEN AFTER THIS TAF PERIOD.
EXTENDED AVIATION OUTLOOK...A FRONT WILL MOVE ACROSS THE AREA
FRIDAY NIGHT INTO SATURDAY. ALTHOUGH PRECIPITATION IS EXPECTED
TO BE LIMITED, BREEZY W/SW WINDS ARE EXPECTED FRIDAY EVENING
SHIFTING TO A NORTHERLY DIRECTION ON SATURDAY.
