Area Forecast Discussion National Weather Service Melbourne FL 412 AM EDT Tue May 11 2021

DISCUSSION. . Increasing Rain Chances Mid To Late Week .

Today . High pressure currently sits over the western Atlantic waters, in addition to, a weak surface high over the eastern Gulf of Mexico. Surface analysis charts also show a decaying wave upstream of east-central Florida with the low center situated over South Carolina with the associated frontal boundary stretching into the Deep South. The area remains dry with dry air winning out as seen on the 00Z observed skew-Ts. Soundings indicated an unstable airmass in place ahead of the slowly approaching frontal boundary with surface and MUCAPE over 3,000 J/kg, as well as, low- to-moderate bulk shear. Current temperatures are in the low-to- mid 70s with dew-points in the upper 60s and low 70s.

As we head into the afternoon hours, the region will remain in between the two high pressure centers which will help cause a sea breeze collision this afternoon and into the early evening hours. However, keeping persistence, model trends, and current observations in mind, dry air will likely keep things contained for the most part this afternoon/evening. With that said, I've trended towards the lower end of model guidance for PoPs this afternoon/evening and kept a chance for isolated showers and storms with daytime heating and sea breeze interactions helping trigger precipitation to develop this afternoon. Any storms that are able to develop, will have the potential to produce gusty winds, cloud-to-ground lighting, and heavy rainfall. Highs will once again be above normal today as southerly flow continues to advect warm air ahead of the frontal system. Highs will reach the upper 80s to low 90s.

Tonight . Overnight, showers and storms will come to an end within a few hours after sunset as the atmosphere stabilizes and as drier air moves into the lower atmosphere. East-central Florida will stay mostly dry overnight with high pressure continuing to be the main influence over the region. Low temperatures will stay warm with partly cloudy skies and southerly flow. Temperatures will drop into the low-to-mid 70s overnight.

Wed-Fri . Increased moisture along with transiting mid level disturbances will help increase coverage of showers and storms at midweek. The upr flow pattern wl become broadly cyclonic while amplifying further late into the work week. Guidances continues to suggest rain chances increasing daily, becoming likely across a large portion of the area during Thu. Additionally, thermodynamic and moisture parameters along with favorable steering level winds wl lead to few strong storms, with small hail and gusty winds on Thu. Expect afternoon highs in the 90s Wed, cooling to the 80s Thu and even cooler Fri in the wake of a passing frontal boundary. Showers will taper during Fri as a drier post-frontal airmass makes it well into the area.

Extended . The upcoming weekend shows a brief return to drier conditions over most of the area as Mid Atlc high pressure builds Swd Sat. Redevelopment of a mentionable shower chance expected across southern and inland areas, as well as the Atlc waters Sun-Mon building Nwd across the remainder of the region well into the following week expected as as onshore flow veers and high pressure becomes established near Bermuda in a Summerlike pattern.

AVIATION. VFR conditions are expected through the TAF period. A chance for isolated showers/storms exists mainly over the northern TAF sites this afternoon, however, confidence isn't high enough to add thunderstorms to the southern TAF locations at this time. Winds will stay light from the east-southeast through the forecast period - becoming light and variable during the nighttime hours.

MARINE. Today-Tonight . The ridge axis will continue to stay over the western Atlantic which will keep southerly winds around 5-10 knots over the coastal waters today, with seas around 2-3 feet expected.

Wed-Fri . Generally favorable conditions for open water navigation Wed-Thu. A frontal boundary during Fri, followed by building winds behind the front will create choppy seas and likely headline conditions late in the week and into Sun over the marine area.

Extended . A long period of onshore flow is shown during next week as high pressure becomes established near Bermuda and WWD. Winds and swell will likely bring headlines for hazardous conditions for most of the local waters at least the early portion of next week.
