High Risk of Rip Currents Continues at Area Beaches Today
Currently...Dry and more fall-like out there this morning, at least by Florida standards. Dewpoints in the 60s are making it feel more comfortable and this combined with light winds and clear skies are allowing temps to fall into the mid to upper 60s, with some low 60s already occurring NW of I-4. At Orlando International Airport the temperature has fallen to 69 degrees this morning, which is the first time below 70 degrees at this site since June 6th!
Today-Tonight...Northerly flow to the west of TS Ophelia, which is nearing the North Carolina coast early this morning, has ushered in a much drier airmass across central FL. GOES TPW imagery shows PW values of around 1 inch or less from Brevard and Osceola counties northward, and up to 1.3-1.4 inches across the southern Treasure Coast. This drier air will keep rain chances out of the forecast for much of the area today, except across southern portions of Okeechobee County and the Treasure Coast where isolated showers and a storm or two may still be possible this afternoon (Rain chances around 20-30 percent).
High pressure then nudges in north of the area behind landfalling Ophelia today, with winds becoming onshore across the area later today into tonight. Additionally, flow above 850mb becomes more southerly in response to a mid level cut off low developing over the southeast Gulf, which will allow deeper moisture south of the area to slowly shift back northward into tonight. This will increase rain chances, up to 30-50 percent along the Treasure Coast, where low level onshore winds may be able to transport scattered showers onshore, with isolated thunderstorm development also possible.
Skies will be mostly to partly sunny today, with highs reaching the mid to upper 80s. Developing onshore flow tonight will not allow temps to fall quite as low as this morning's min temps, with lows forecast in the upper 60s to low 70s for much of the area, except mid 60s NW of I-4.
Sunday-Tuesday...Rain chances gradually increase on Sunday but generally ramp up Monday and Tuesday. Moisture will be on an upward trend, with 1.6" to 1.8" PW Sunday, increasing to 2.0" and higher into the first half of the week. Low-level winds are modeled to be rather weak, so storm-scale boundary collisions and outflow boundaries will likely dictate storm motions. Rain and storm chances will be maximized during the afternoon and early evening hours, especially along the east coast sea breeze as it advances inland each day. Slightly more upper level wind support moves into place Tuesday and Wednesday for organized convection. However, 500mb temperatures will remain marginal and steady state, between -6C and -8C during this timeframe. As is routinely advertised, storm threats will primarily include gusty winds, lightning strikes, and localized heavy rainfall.
High temperatures are forecast to be near normal values for late September, with lows in the upper 60s/mid 70s Sunday and Monday, warming to the 70s across much of the area Tuesday and Wednesday.
Wednesday-Friday...High pressure over the Bahamas will slide east Wednesday into late week with modest 500mb height falls over the eastern CONUS. The GFS is slightly more aggressive with troughing over the eastern U.S. Thursday and Friday, as compared to the EURO solutions. Either way, it looks to remain a convectively active pattern through the week with a frontal boundary stalled across the Florida Peninsula Wednesday and Thursday. This feature is forecast to move south of the local area Friday as northeasterly winds increase, due to a tightening pressure gradient.
High temperatures will remain near normal through week's end but could hold in the mid to upper 80s each day, due to increased cloud cover and associated rain chances. What will be most noticeable is the increase in humidity all week, making conditions feel very summerlike once again.
MARINE
Issued at 445 AM EDT Sat Sep 23 2023
Today-Tonight...Winds have diminished to around 5-10 knots over the waters out of the N/NE, and will veer to the E/NE this afternoon and tonight. However, hazardous seas up to 5-7 feet nearshore and up to 7-9 feet offshore linger across the waters this morning. A Small Craft Advisory continues for the entire coastal waters through mid afternoon. Seas will be gradually subsiding through the day, which will allow the SCA over the nearshore waters to drop by 4PM, and for the offshore waters by 8PM this evening. Seas of 4-6 feet across the waters by late this evening will then fall to 3-5 feet by late tonight.
Drier airmass across the area will largely keep rain chances out of the forecast for much of the area, except south of Sebastian Inlet where showers and isolated storms will still be possible, especially this afternoon and into tonight as moisture gradually increases back northward overnight.
Sunday-Wednesday...Onshore winds are forecast daily through the period, reaching 10-12 kt each afternoon. Expect a developing east coast sea breeze with rain chances gradually increasing over the local waters each day, especially Tuesday and Wednesday. Seas generally 2-3 ft, up to 4 ft over the Gulf Stream Sunday and again late Wednesday.
FIRE WEATHER
Issued at 445 AM EDT Sat Sep 23 2023
Min RH values will fall as low as the mid to upper 30s along and NW of I-4 this afternoon due to the drier airmass across the area.
However, winds will be relatively light around 5-10 mph, initially out of north this morning and then becoming N/NE this afternoon.
Onshore flow will then gradually lead to an increase of moisture, as well as shower and thunderstorm chances, with Min RH values then forecast to remain above critical levels Sunday and into next week.
AVIATION
(06Z TAFS)
Issued at 445 AM EDT Sat Sep 23 2023
Drier airmass across the area will keep conditions VFR for much of the area today into tonight. Low end rain chances linger near to south of KFPR today, and will increase gradually from the south northward overnight as moisture increases. Isolated to scattered showers may be able to develop this afternoon into tonight, especially along the Treasure Coast overnight, with isolated storms also possible. For now only have VCSH in the TAFs for KFPR/KSUA, and VCTS between 18-22Z for KSUA into this afternoon.
Light northerly winds this morning will veer to the E/NE through the afternoon, with speeds up to 8-10 knots.
HYDROLOGY
Issued at 445 AM EDT Sat Sep 23 2023
The Saint Johns River at Astor continues to oscillate around Action Stage of 2.0ft this morning and may continue to linger around this level through this afternoon before gradually falling and remaining below Action Stage tonight into Sunday.
