DISCUSSION
Issued at 440 AM EDT Mon May 13 2024

Key Messages:

-Marginal Risk for a few strong to severe storms this afternoon and evening.

-Potential for strong to isolated severe storms will continue through mid-week.

-Unseasonably hot conditions Tuesday into late week, with highs in the 90s most days and peak heat index values rising to 100-105.

Today & Tonight...

Synoptic Overview:

A fairly amplified weather regime continues to affect the eastern half of the U.S. A weak shortwave ridge axis is approaching Florida this morning, out ahead of a stout subtropical jet segment along the Northern Gulf Coast. To the west, an upper trough is slowly moving across the High Plains. At the surface, high pressure is now moving into the W Atlantic. As the high moves seaward, moisture will continue to increase today as boundary layer flow veers toward the SE. The ridge axis will essentially reside overhead this afternoon and tonight, but the mid-level zonal flow will continue to increase as the subtropical jet encroaches, exceeding the 90th percentile of climatology at H5. Additionally, a weak perturbation is evident on some guidance this afternoon, perhaps convectively enhanced from a complex of storms off to our northwest. A robust sea breeze circulation is forecast by hi-res guidance, with a collision favoring the center of the peninsula.

Sensible Weather & Impacts:

Today...

We begin the week with an opportunity for some needed rain, but that will come with a risk of storms. Despite relatively poor mid-level lapse rates beneath the ridge, HRRR members indicate sufficient moisture (PW > 1.5") and instability (MLCAPE 750-1250 J/kg) for convection to develop on the sea breeze collision this afternoon and early evening. Combine the potential weak impulse aloft riding through here at peak heating, and we have come up with increased rain/storm chances, now at 40-60%. 0-6km shear increases to 40+KT, and 0-3km helicity will approach 200 m^2/s^2. Thus, a few storms could become strong to severe. There is at least a 5% risk of gusty winds and large hail, with the SPC highlighting a Marginal (level 1 of 5) risk today. A tornado or two cannot be ruled out: much of the helicity resides in the 0-3km layer, but boundary collisions could introduce localized pockets of higher 0-1km helicity and surface vorticity. Storms are forecast to develop after 2 PM over the interior, with the mean flow aloft favoring storm motions back toward the East Coast in the early evening. Frequent lightning is expected, and anvils propagating toward the coast may cause strikes well away from the storm cores.

It will be breezy this afternoon, especially on the coast with SE gusts of 15-25 MPH. This will hold temperatures in check along the I- 95 corridor for one more day, with mid 80s at the coast warming to the low 90s over the interior. Heat indices may approach 100F along the Kissimmee Basin to Okeechobee.

Tonight...

Will hang onto a few showers and storms along the coast in the early- mid evening hours before most areas dry out for the overnight period. Fresh SE flow will begin to veer more SSE overnight, keeping low temperatures above normal with low 70s over the interior and mid/upper 70s on the barrier islands. Another ripple of energy in the subtropical jet will fire off rounds of storms to our northwest late tonight. A minority of CAMs suggest this activity could approach Lake/Volusia counties overnight. Will handle this with a 20% storm chance after 5 AM in those areas.

Tuesday-Wednesday...Warm front will have lifted north of the area by Tuesday morning, with another cold front moving into the southeast U.S. into Tuesday/Tuesday night. This will lead to unseasonably hot conditions with highs into the low to mid 90s over much of the area, and peak heat index values up to 100-105. Breezy S/SW flow will develop into Tuesday afternoon, and should the east coast sea breeze be able to develop, it will likely remain stalled near the coast with the slight offshore component in the low level winds. A moist airmass will remain in place across the area, with PW values around 1.7 to 1.9 inches. This should be sufficient for at least scattered showers and storms to develop, especially into the afternoon, with PoPs around 40-50 percent for much of the area.

However, some of the CAM guidance also showing a band of showers and storms from MCS pushing through north FL into northern portions of east central FL. The HRRR is currently an outlier showing a much faster arrival of this system into early Tuesday morning. Therefore, there remains some uncertainty with overall evolution of convection into Tuesday. Strong to isolated severe storms will be possible regardless, especially near to north of Orlando where 850-700mb W/SW flow will be a little stronger up to 30-40 knots. However, late day interactions with the east coast sea breeze may enhance convection along the coast before it shifts offshore. SPC for now has extended the Marginal Risk for severe weather southward into Lake, Volusia and Seminole counties for Tuesday.

The weakening front will eventually settle and stall across northern portions of east central FL into Wednesday/Wednesday night.
Additional showers and storms may develop ahead of this front later into Tuesday night/early Wednesday, especially near to north of Orlando. Then expecting increasing coverage of convection through the day. Highest rain chances, around 60 percent will reside across Osceola/Brevard counties northward, closer to the front and where greatest moisture will reside, and 50 percent to the south. Strong to isolated severe storms will again be possible as elevated westerly flow (around 30- 40 knots from 925-700mb)
and cooler temps aloft (-10 to -11C at 500mb) will produce a threat of strong to locally damaging winds and coin-sized hail with any storms that form. SPC has a Marginal Risk for severe weather across much of central FL. Greater cloud cover and potential earlier start to showers and storms across north central FL will keep highs limited to the upper 80s/low 90s, but hot and muggy conditions expected to continue for Okeechobee County and the Treasure Coast where max temps are forecast to reach the mid 90s with peak heat index values closer to 104-108 (nearing Heat Advisory thresholds).

Thursday-Sunday...Greatest moisture begins to focus across southern portions of east central FL south of stalled front across the region into Thursday. Scattered showers and storms will still be possible, especially into the afternoon near to south of Orlando where PoPs will range from 30-50 percent. Then as front and deeper moisture lift back north into late week, potential for scattered afternoon showers and storms return area-wide, with chance PoPs (30-50 percent) across all of east central Florida Friday and into the weekend. Hot conditions continue through the period, with highs into the 90s and humid conditions producing peak heat index values around 100-105 each afternoon.

AVIATION
(06Z TAFs)
Issued at 440 AM EDT Mon May 13 2024

Quiet weather is forecast through 18Z, with SE winds increasing to 10-15 KT this morning. For the coastal terminals, gusts to 18-24 KT are expected after 14Z. Scattered storms are then expected to develop, with 40-60% coverage around Greater Orlando from 13/20Z- 14/00Z. This activity will tend to propagate toward the East Coast terminals after 21Z through around 14/02Z. Attempted to capture this timing in the TAFs. One or two storms could be strong to severe in the late afternoon/early evening.

MARINE
Issued at 440 AM EDT Mon May 13 2024

Today-Tonight...High pressure pushes offshore today as a weather disturbance moves into the Red River Valley. In response, southeast winds freshen over the marine area to 15-20 KT this afternoon and tonight. Small craft will need to exercise caution this afternoon across much of the local Atlantic; a Small Craft Advisory will go into effect for winds around 20 KT beyond 20 NM after 8 PM. Seas build to 3-4 FT this afternoon and tonight, with short periods contributing an enhanced chop. Scattered storms over the mainland will attempt to push toward the coast this evening.
In so doing, offshore-moving storms with erratic/gusty winds and lightning could affect the coastal waters from 5 PM to 10 PM this evening. The highest chance of this activity is north of Sebastian Inlet. Otherwise, Intracoastal and inshore waters will be choppy at times through the next 24 HR.

Tuesday-Friday...Poor to hazardous boating conditions will persist across the waters into Tuesday/Tuesday night as S/SE flow of 15-25 knots veers to the S/SW into the evening. Seas will be choppy with a dominant period of 5-6 seconds and wave heights up to 4 to 6 feet offshore. A Small Craft Advisory will continue for the offshore waters through late Tuesday night, and may have to consider expanding to at least the nearshore waters of the Treasure Coast for Tuesday afternoon into Tuesday night.

Poor boating conditions look to persist offshore for much of Wednesday into Wednesday night as offshore flow remains up to 15-20 knots. However, more favorable boating conditions expected into late week as winds diminish into Thursday morning before becoming onshore late in the day and veering to the S/SE into Friday, with speeds around 5-10 knots. Seas 3-5 feet on Wednesday fall to 2-4 feet Thursday and 1-2 feet on Friday.

Scattered offshore moving storms will be possible each day, especially during the afternoon and evening hours, with some strong to isolated severe storms possible on Tuesday and Wednesday.

FIRE WEATHER
Issued at 440 AM EDT Mon May 13 2024

Today-Tonight...SE winds increase to 10-15 MPH, with gusts to 25 MPH along the coast. This will feed more moisture into the area, with afternoon RH readings only falling to 45-50% along the Kissimmee Basin (higher elsewhere). Scattered storms are forecast to develop in the afternoon and evening hours. Frequent lightning strikes are possible with this activity with erratic/gusty winds beneath them. Some areas will get needed wetting rains today, with rain coverage at 40-60%.

Tuesday-Friday...Increasing moisture will keep Min RH values above critical values through the work week, but unseasonably hot conditions with highs in the 90s will at times lead to RH values as low as the low to mid 40s over the interior during the afternoon hours. Isolated to scattered showers and storms will continue each day, with some strong to isolated severe storms possible on Tuesday and Wednesday. Winds will be breezy out of the S/SW on Tuesday and out of the W/SW on Wednesday.
