DISCUSSION.

. Sunny and Much More Comfortable Today .

Current . Impressively, the pre-frontal shower band held together and produced measurable rainfall across pretty much the entire CWA, with several locations picking up a few tenths of much needed rainfall, anding what was otherwise a dry, hot March. As anticipated, lighting was quite limited, as just a couple strikes were indicated by LDS over land, while a little more activity took place out over the near shore Atlantic. Multichannel IR imagery shows some post frontal clouds bands dropping SE across the northern-central CWA.

Post-frontal dry/cool air advection starting to take hold NW of I-4, where temperatures have fallen into the L60s with mainly L70s to the south. Noticeably more comfortable air mass will continue to spread south through sunrise.

Today-tonight . Sunny and much more pleasant today with a steady northwest wind veering to north, breezy at times along the coast through mid day. Max temps to start off April will actually be below normal for all but the south interior, mainly in the M-U70s, except for L70s near the Volusia coast over L80s interior south. Winds may briefly veer onshore along the Treasure Coast before snapping back to N-NNW tonight in a developing nocturnal drainage flow. Widespread mins in the 50s, with a few spots over NE Lake/NW Volusia dropping to near 50F.

Thursday-Friday . High pressure centered over the eastern U.S. will veer post frontal winds to the northeast, providing welcome relief from near record temperatures, at least for a few days. In fact, near normal temperatures will end the week. Highs in the mid to upper 70s along the coast and near 80 inland on Thursday, with slightly warmer highs in the low 80s on Friday afternoon across the interior. Lows each morning will fall into the mid to upper 50s, except the low 60s along the immediate Treasure Coast and low 50s in rural parts of interior east central Florida. No precipitation is expected, with RH values remaining dry.

Saturday onward . Western Atlantic high pressure will be the dominate force through the middle of next week. Temperatures warming into Saturday into the mid 80s inland and upper 70s to low 80s along the coast, with easterly flow and dry conditions continuing. Then, a shortwave trough will ride along the top of mid/upper level high pressure centered over the Gulf of Mexico on Sunday. Models continue to weaken this shortwave, if they have it at all. The GFS shows modest mid level vorticity making it into area; however, limited vorticity coupled with little available moisture means that POPs have been scaled back again, with only a slight chance of showers north of I-4 during the day on Sunday. Thunderstorms look unlikely, with forecast soundings indicating a robust warm nose in the mid levels. While precipitation chances will leave something to be desired, there will be enough of an increase in clouds to cap highs in the upper 70s to low 80s.

After that, Monday begins a warming trend that will continue through the end of the forecast period. Surface high pressure lingers in the western Atlantic, then flattens mid week, with its ridge axis draped across the Florida peninsula. This will cause winds to veer southerly early in the week. Thus, above normal temperatures return, reaching the upper 80s to near 90 by Tuesday, as warmer air funnels in from the south. Dry conditions look to persist, with no mentionable POPs through Tuesday.

AVIATION. Band of clouds showers with MVFR CIGs BKN-025-030 will quickly move SE of SUA by 09Z. A trailing band of SCU CIGs BKN025- BKN035 wil drop across the northern and central aerodromes through through about 12Z. Otherwise, VFR/SKC spreading N-S throughout the day. Wind gusts 20-22KT from 320-350, especially for the coastal corridor.

MARINE. Today-tonight . As is typical in an offshore flow regime, sustained wind speeds of 20-25kt only produce seas 2-4ft nearshore and 5-6ft well away from the coast. As winds veer to NW-N today. higher seas will spread shoreward, briefly reaching 7-8ft in the Gulf Stream. Winds and seas will start to subside (4-6ft) as winds veer to NNE tonight.

Thursday-Friday . Hazardous boating conditions will end the week, as seas are slow to subside flowing the persistent breezy northerly flow behind the front. Seas 5-7 ft Thursday afternoon will persist overnight into Friday, before decreasing to 4-6 ft Friday afternoon. Highest seas will be in the Gulf Stream waters, where they may increase to 8 ft for a time late Thursday night. Winds NE/NNE around 10-15 kts Thursday afternoon will continue through early Friday morning, when speeds will diminish to 5-10 kts, before increasing again Friday afternoon.

Saturday onward . Guidance continues to indicate a large swell building into the local waters this weekend, due to a large north Atlantic storm. While boating conditions still look to be dangerous, seas have been adjusted down to a maximum of 10 ft beginning late Saturday night. Nonetheless, hazardous boating conditions look likely for the weekend, with easterly flow. Swell heights will be dependent on the strength and position of this north Atlantic storm, so it bears watching as the week progresses.

FIRE WEATHER. Strong post frontal dry air advection will push RH values down to between 27-35% for all but the immediate coast this afternoon. While winds will be closer to 15 mph through late morning speeds are expected to drop below RFW criteria during the period of lowest RHs this afternoon. For the time being, will hold off on any fire weather watch. Day shift can reassess critical wind/RH potential for this afternoon.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
