GMZ700 Synopsis For The Suwannee River To Okaloosa-walton County Line Out To 60 Nm 317 Am Edt Thu Apr 22 2021
Synopsis.. Active weather pattern shaping up for the end of the week and into the weekend with poor boating conditions expected. Main concerns are elevated winds and seas due to a frontal system moving through the region on Saturday. Advisory conditions are likely Friday night into Sunday morning as strong southerly flow develops. Widespread showers and storms are also expected, some which could become severe on Saturday. Rain clears up into early Sunday and winds and seas will become lower by next Monday.

AVIATION. [Through 12Z Friday]
VFR conditions expected through the next 24 hours. Dry, post-frontal airmass has cleared skies with the exception of a batch of cirrus currently drifting overhead. By 14z, skies will be clear as cirrus moves offshore. Expect winds to be strongest through the morning hours as they veer from N to NE, with sustained winds of 10-15 knots and gusts up to 30 knots. Winds will decrease through this afternoon as a progressive Atlantic sea breeze pushes inland, veering winds further to the ENE. Sea breeze expected to reach I-95 corridor by 19z and then the I-75 corridor by 01z/02z. Winds will become light at inland sites overnight tonight but remain breezy at airfields along the immediate coast with persisting onshore winds.
PREV DISCUSSION [352 AM EDT].
NEAR TERM [Through Tonight].
A low level ridge of high pressure will build eastward over the Southeast through the day, then move closer to the mid-Atlantic coastline overnight. This will push in a much colder, drier air mass. We'll have a chilly start this morning with lows in the 40s to low 50s, with strong winds from the north making it feel even colder- like upper 30s to mid 40s across much of the region. Winds will lower quickly in the afternoon as the ridge settles briefly over Nrn GA, but with the cold, dry airmass in place, we'll still struggle to warm into the the upper 60s to mid 70s. Very dry conditions will also mean enhanced fire danger, particularly in inland SE GA where minimum RH values will be around 20-25% and fuels are dry.
SHORT TERM [Friday Through Saturday].
Friday, high pressure to the northeast will keep the area dry through the day as cloud cover increases ahead of the next frontal system. Surface winds will shift to become southeasterly Friday afternoon, which will bring high temperatures up into the lower 80s along the I-75 corridor. Breezy onshore winds will keep highs along the I-95 corridor cooler in the 70s. Friday night, a warm front stretching from a low pressure center in the southern plains, over the eastern Gulf of Mexico, and towards southern Florida will lift northeastward towards the area. A few showers will be possible overnight in SE GA as isentropic lift strengthens. Overnight temperatures will be warmer than the previous two nights with lows in the lower 60s inland and middle 60s at the coast.
Saturday, there will be a risk of severe weather, primarily in SE GA and inland NE FL north of I-10. The low over the central plains will track towards the Mid-Atlantic region, which will bring the approaching warm front north across the area in the morning/early afternoon followed by a trailing cold front from the northwest. The strong low will be accompanied by a 50-70 knot low level jet, which will develop a strongly sheared environment in SE GA and NE FL north of I-10 with moderate shear over the rest of NE FL as well. Temperatures behind the warm front will rise into the 80s and dew points will rise into the 60s. Instability will rapidly increase through the afternoon, and CAPE is expected to be upwards of 1500 J/kg.
This environment will be favorable for severe thunderstorms capable of producing strong winds, hail, and isolated tornadoes. Southwesterly flow behind the warm front will also bring moisture from the Gulf of Mexico over the area, which could contribute to heavy rainfall. Severe potential will be greatest over SE GA and inland NE FL north of I-10 where strong shear and high CAPE values will be co-located with convergence caused by the lifting warm front. Severe potential will be lower over the rest of NE FL, but severe storms will still be possible due to moderate shear and instability in the warm sector between the warm and cold fronts. The cold front will continue to cross the area through early Sunday morning. Overnight lows Saturday night into Sunday morning are expected to be in the 60s.
LONG TERM [Sunday Through Thursday].
The trailing cold front will cross the area early Sunday, which will continue rain and storm chances through the morning hours. High pressure will build in from the north after the cold front passes. High pressure ridging over the eastern United States is expected to continue through the middle of next week, bringing dry weather through Wednesday. Models suggest the next chance for rain will come with an approaching cold front towards the end of the week. High temperatures through this period are expected to be in the 70s and 80s, and low temperatures are expected to be in the 50s and 60s.
MARINE.
High pressure to the northwest will cause strong northeast winds around 20 knots this morning, decreasing in the afternoon as the high pressure center shifts closer and the pressure gradient weakens. Small Craft Advisories are in effect until 10 AM. The high will shift off the Carolina coast Friday, and winds will become easterly. Winds will begin to increase again Friday night as the high moves east of the area waters and a warm front approaches from the southeast. Saturday, winds will continue to strengthen as the warm front lifts north and a cold front approaches from the northwest. Small Craft Advisories may be needed as southerly winds pick up on Saturday, and showers and strong thunderstorms will be possible in the afternoon and evening. Winds will shift to southwesterly Saturday night as the cold front gets closer, then shift to westerly after the front passes early Sunday morning. Winds will start to decrease Sunday afternoon, and high pressure will build to the north through early next week.
Rip Currents: High Risk of rip currents Today at NE FL beaches, decreasing to Moderate Friday. Moderate Risk at SE GA beaches through Friday.
FIRE WEATHER.
Elevated Fire Danger in inland Southeast Georgia Today. Long duration Critically Low Humidity Today across inland Southeast Georgia and the Suwannee Valley.
A ridge of high pressure will approach the region today, bringing in a significantly colder and drier airmass, but also lowering our winds noticeably in the afternoon. VERY dry conditions will be in place this afternoon with minimum RH values in the 20-25% range across inland southeast Georgia and upper Suwannee Valley and 25-30% across the lower Suwannee Valley. In inland southeast Georgia, fuel moistures are also forecast to hover near the 6% threshold, so there is an elevated fire danger there again today. On Friday, onshore flow will begin to gradually return moisture to the region, but RH values will be around 25-30% in inland southeast Georgia again. This weekend, a strong storm system will move through the region, bringing thunderstorms to the area Saturday afternoon and Saturday night, possibly lingering into Sunday morning.
HYDROLOGY.
Runoff from weekend rainfall will result in portions of the lower Santa Fe River reaching or briefly exceeding flood stage on Today and Friday, particularly in the vicinity of O'Leno State Park.
