...Dry and Warm Weather Continues with Near Record Highs This Weekend...
DISCUSSION
Issued at 208 PM EDT Fri Apr 19 2024
Currently-Tonight... High pressure (1020mb) remains over the western Atlantic, as well as over the eastern Gulf of Mexico. The sea breeze is currently pushing inland with east to southeast winds at 5-10mph across east central Florida. The dry and quiet weather for east central Florida continues with Goes-16 satellite imagery showing partly cloudy skies and scattered low to mid level clouds. Current temperatures are in the low to upper 80s with dew point temperatures in the low 60s to upper 60s.
Winds are expected to become light and variable overnight with patchy fog forecast to develop, mainly between 4am and 8am across Lake, western Orange, northwest Osceola, western Seminole, and northwest Volusia counties. Visibilities will have the potential to drop to 1 mile or less at times. If you encounter fog, remember to use your low beam headlights and leave plenty of distance between you and the vehicle in front of you. Overnight lows are forecast to drop into the low to upper 60s under mostly clear skies. Although, scattered low stratus will be possible into Saturday morning north of I-4.
Saturday... High pressure over the western Atlantic and eastern Gulf of Mexico will continue to influence east central Florida into Saturday. Offshore west to northwest winds at around 5-10mph are expected to veer onshore into the afternoon as the east coast sea breeze pushes inland and eventually reaches the western portions of central Florida into the evening hours. Afternoon highs in the upper 80s to low 90s along the coast and in the low to mid 90s well inland west of I-95 are forecast with heat index values around the same values.
Sat Night-Sun Night...Zonal flow aloft with occasional shortwave impulses traversing the region with a vigorous mid-level low strengthening and swinging into the Tennessee Valley late in the period. At the surface, a weakening pre-frontal trough to the north will lie quasi-stationary, but then get a kick southward into north- central FL Sun night. Light offshore flow, except onshore with sea breeze formation Sun afternoon along the immediate coast, will veer NW/N Sun late overnight across most of ECFL. We currently maintain a SCHC for showers and lightning storms - mainly across the I-4 corridor Sun night as moisture gets a modest bump upward. Overnight lows well into the 60s both Sat/Sun night. High temperatures, near records, forecast again for Sun - in the U80s to around 90F at the coast and L90s (perhaps a few M90s) inland. Forecast low humidities will keep Heat Index values close to actual temps.
Mon-Fri...The aforementioned boundary will get a bigger kick southward thru central/south FL on Mon, with aid from an upper level trough, followed by a period of weak high pressure. The mid-level flow stays W/NW thru the period, but absent of any decent shortwave activity. SCT showers and ISOLD lightning storms forecast for Mon.
Dry over land Mon night-Wed morning, then perhaps some ISOLD convective activity Wed/Thu aftn/eve due to an increase and moisture and sea breeze collisions for mainly the Treasure Coast, though the ECMWF is the drier of the medium range model solutions presently.
Confidence low though and otherwise dry conditions mostly, after- all, we are still in the climatologically driest month of the year.
A small cool-down for Mon, with U70s-L80s along/north of I-4 and M- U80s southward toward Okeechobee/Martin-Saint Lucie counties. U70s- L80s along the coast on Tue with M80s well into the interior. A warming trend Wed-Fri as highs along the coast gravitate toward the L80s with M-U80s into the interior. For mins, L60s most places Tue- Thu mornings, except U50s for portions for north Lake/NW Volusia counties. Otherwise a gradual increase thru the 60s for the remainder of the period for lows.
AVIATION
(18Z TAFs)
Issued at 208 PM EDT Fri Apr 19 2024
Primarily VFR conditions are forecast through the TAF period.
However, patchy fog is possible at KLEE which will have the potential to reduce visibility to 3 miles or less at times Saturday morning. Offshore west-northwest winds will veer onshore with the east coast sea breeze pushing inland into the afternoon at 5-10kts Saturday.
MARINE
Issued at 304 PM EDT Fri Apr 19 2024
Currently-Saturday.... Favorable boating conditions are forecast through Saturday afternoon with high pressure over the western Atlantic. Offshore west to southwest winds will veer east- southeast into the afternoon Saturday at around 8-15kts with the east coast sea breeze. Seas will build to 1-3ft with up to 4 ft offshore and nearshore southern Brevard and Treasure Coast waters into Saturday morning.
Sat Night-Wed...High pressure will keep a pre-frontal trough north of the local waters thru late Sun, then a push from energy aloft will finally force this feature south down the peninsula on Mon. Weak high pressure will follow the front Tue-Wed. We may see SCT showers and ISOLD lightning storms enter the picture Sun night (north) - Mon night surrounding the front. We will see another sea breeze on Sun, but stiffer WRLY flow may keep this feature pinned closer along the coast. Southerly winds will gradually veer ahead of the approaching boundary, then continue NW/N behind it on Mon, transitioning further to NERLY on Tue, E/ESE Tue night- Wed. Speeds approach 14-18 kts offshore Sat overnight, and may increase 15-20 kts late Sun-Sun night, but otherwise are largely 10-16 kts for in between and Mon-Wed. Seas mainly 2-4 ft, then 3-5 ft (6 ft Gulf Stream) Mon night-Tue night, becoming 3-5 ft early Wed - gradually 2- 4 ft again areawide by Wed afternoon.
FIRE WEATHER
Issued at 304 PM EDT Fri Apr 19 2024
Saturday (modified previous discussion) A broad area of high pressure will remain in place across the Florida peninsula through the weekend. Dry conditions will continue across east central Florida as a result. Minimum RH values are forecast to remain in the 30 to 45 percent range west of I-95 across the interior Saturday with winds continuing to be light out of the west- southwest and becoming variable at times, until the east coast sea breeze develops and moves inland, leading to winds turning to out of the south-southeast at around 10 mph.
Sun-Thu...High pressure will keep a weak frontal boundary north of the area for one more day, Sun, as min RH values plummet into the M- U30s W of I-95 and 40-45pct eastward toward the coast. ISOLD showers and lightning storms forecast Sun night I-4 corridor northward, then SCT showers/ISOLD lightning storms for Mon as the front moves through. Dry conditions then return for Tue-Thu, with min RH values falling into the M-U30s over the interior each afternoon. Wind speeds do not look to be an issue, but there will be variability in wind direction over the extended surrounding pre-frontal, post- frontal, and high pressure moving back into the region following the front. Significant Fire Potential remains Moderate to High thru the period.
CLIMATE
Issued at 304 PM EDT Fri Apr 19 2024
Highs will remain above to well above normal this weekend, reaching the mid 80s to around 90 degrees along the coast and in the low 90s over the interior (mid 90s possible inland on Saturday). These values will be near daily record highs over the next couple of days.
