DISCUSSION

KEY MESSAGE 1
Today looks like the last hot day of the fcst period. High temps in the 80s to around 90 for most of the area. Had to manually boost temps well abv the NBM for the CT and NY coasts. Brought Montauk up by 11 degrees abv the NBM, which may still end up being too little. Still warm and abv normal on Fri, but high temps only in the 70s and low 80s with falling heights and chcs for shwrs and tstms.


KEY MESSAGE 2
A few cells may still pop early this mrng with outflow passing thru the cwa. No upr support so this convection should be limited in extent and intensity.

Unstable today, particularly N and W, but with the lack of a trigger tstm development is expected to be low probability attm. Still something to watch in the mesoscale as the day goes on due to expected CAPE and a lack of CIN. The next best chcs are this eve and tngt as heights fall and the sfc boundary drops swd into the area. The sfc boundary looks a bit too displaced from the upr support tngt to support a solid focus and high confidence in development. Stuck with the NBM pops which are only slight chc.

Timing of the upr trof for Fri seems a bit too early for optimal tstm support attm. A six hour difference could allow for this to act on enough CAPE to produce some strong low topped convection.
For now the NBM was followed which indicates chcs for shwrs thru the day.


KEY MESSAGE 3
Shwrs and embedded tstms likely on Sun with a cold fropa. Timing will determine the nature of any svr threat. The GFS and AI-GFS right now look a little too quick to support a big event with the front already into the area at 12Z. It is still a powerful upr low with a H3 jet modeled at 130+kt, so pcpn is still likely with the sys.

NW winds kick in behind the front and temps plummet by late in the day with lingering areas of rain. The cold pool aloft builds in Mon with 1000-500mb thicknesses around 520dam. The steep lapse rates should allow for at least isold-sct shwrs, possibly mixed with snow or ice pellets. The NBM pops may be a bit too low. Some spots across the interior may drop blw freezing Sun ngt, then much of the area could drop blw freezing Mon ngt. MGJ MOS climo is 39, and the MEX is already producing 29 Sun ngt and 25 Mon ngt.
