Area Forecast Discussion National Weather Service Jacksonville FL 829 PM EDT Thu Apr 22 2021

UPDATE.

Forecast remains on track this evening as high pressure moves north of the region through tonight and then to the northeast on Friday with onshore easterly winds around 10-15 mph near the coast and 5-10 mph inland with high thin cirrus clouds moving in through the day and some scattered stratocumulus near the coast moving inland.

Low temperatures tonight will be cool with 40s north and west of Jacksonville, near 50 along the SE GA coast and low to mid 50s along the NE FL coast. Highs on Friday will be slightly below normal with highs in the low to mid 70s in SE GA and the coast and in the upper 70s over inland NE FL.

Expect a wet and stormy start to the weekend on Saturday with potentially severe thunderstorms moving through much of the area Saturday afternoon and evening as a strong cold front pushes in from the west.

PREV DISCUSSION [717 PM EDT].


Short Term. /through Friday night/ .

High pressure will be centered to the north of the region through Tonight. Subsidence under the ridge will provide for mainly clear skies. The position of the high will yield onshore flow, with the sea breeze pushing well inland this afternoon. Below normal temperatures are expected once again Tonight, especially inland.

The high will then build toward the east northeast Friday into Friday night. A warm front will lift northeast across SE GA Friday night. Moisture will gradually increase through the day Friday, with highs near to a little below normal. The coolest readings will be near the coast due to the onshore flow. The moisture increase will continue through the night Friday night, with dewpoints rising into the upper 50s to lower 60s overnight, and lows trending above normal. A few showers will be possible across SE GA overnight as the warm front lifts through.

Long Term. /Saturday through Thursday/ .

The region will be between high pressure to the east southeast, and low pressure to the northwest Saturday. This pattern will yield an increasingly warm and moist flow from the south to southwest. Dewpoints will rise through the 60s during the day Saturday, with temperatures rising above normal. The combination of the warm and moist airmass will provide for an unstable airmass. A prefrontal trough is expected to develop across GA Saturday afternoon ahead of the main cold front, and drop southeast into SE GA and Suwannee valley of NE FL later in the afternoon and evening. A squall line of strong to severe storms may develop along this boundary. At this time, it looks like line will weaken somewhat as it enters rest of NE FL later into the evening/overnight period with loss of diurnal heating. But the severe potential could shift further south into NE FL if the system speeds up, or the line itself accelerates. With the current timing, much of Saturday morning will be dry across NE FL.

The cold front will push southeast across the region Saturday night into Sunday morning, leaving much of Sunday dry. There is not much of a thermal difference on the back side of the front, so Sunday will be another above normal temperature day, but noticeably drier air will filter southeast through the day.

High pressure will build to the north Sunday night and northeast Monday through Tuesday, with a period of dry weather and temperatures near to a little above seasonal averages.

The high will build to the east Wednesday into Wednesday night. Warmth and moisture will increase across region in this pattern with above normal temperatures. A strong cold front is expected to move into region from the west later in the week. At this point will introduce precipitation potential on Thursday, but chances will be on the low end, until greater forecast confidence on timing of system.

AVIATION. [Through 00Z Saturday]

VFR conditions will continue through the end of the 00Z TAF period as high pressure moves north of the region tonight and then situates northeast of the region on Friday. Winds tonight from the northeast will remain elevated at KSSI and KSGJ around 6 to 8 knots while inland TAF sites decouple with near calm, variable winds after 03Z-04Z. Winds will increase after 15Z with partly to mostly sunny skies. Few to scattered low level clouds around 3.5-4.5 kft will develop and push inland in the easterly flow off the Atlantic with moisture levels slowly increasing as high pressure moves more offshore towards the east north east by the end of the TAF period with increasing high level clouds over the terminals.

Marine.

High pressure will be north of the region through Tonight, then to the northeast Friday, and more toward the east northeast Friday night through Saturday. A line of strong to severe thunderstorms is expected to sweep across the area Saturday afternoon into Saturday night, just ahead of a cold front. The cold front will pass through overnight into Sunday morning. High pressure will build to the north northeast Monday into Tuesday, then more toward the northeast Wednesday into Thursday. A cold front will move east across the region late in the week. Rip Currents: SE GA Moderate through Friday NE FL High Today, Moderate Friday
