KEY MESSAGES

- Localized heavy rainfall may occur with showers & thunderstorms into the early morning hours.

- Most places can expect rain each day through most of the next week.

UPDATE

Issued at 145 AM EDT SAT MAY 23 2026

No significant changes were made to the forecast with mainly just the inclusion of the latest obs and trends for the T/Td grids. Did also tweak the PoPs through the rest of the night given the current radar and high resolution CAMs guidance. These minor adjustments have been sent to the NDFD and web servers along with a freshening of the zones.

UPDATE Issued at 1155 PM EDT FRI MAY 22 2026

Hourly grids were freshened up to account for recent radar trends and observations. This accounted for the ongoing dryslot. Some of the guidance has some redevelopment overnight, and thus current forecast pops increase toward dawn, especially in the west.

UPDATE Issued at 855 PM EDT FRI MAY 22 2026

Adjustments were made to pops to account for recent radar trends while hourly temperatures were freshened up based on recent observations. Locally heavy rainfall remains a threat tonight where rounds of rain move repeatedly over the same locations.

LONG TERM

(Sunday through Friday) Issued at 452 PM EDT FRI MAY 22 2026

The main belt of stronger flow aloft will retreat to the north early in the week and the aforementioned front from the short term section will lose momentum. It is expected to stall in our area and allow for a daily threat of showers/thunderstorms. An upper trough should deepen over the northeast CONUS at the end of the week, which could allow for a southward push of drier air finally making it here. The POP is lower on Friday to allow for this possibility.

AVIATION

(For the 06Z TAFS through 06Z Saturday night) ISSUED AT 220 AM EDT SAT MAY 23 2026

At issuance time, conditions were mostly VFR with MVFR holding on at KSYM. Convection is in a lull, at present, but expectations are that it will expand into dawn as the sfc low moves nearly overhead. Reductions to MVFR or IFR conditions can be anticipated in any of these renewed showers, along with some roving patches of fog, into dawn. Stronger pockets of convection should return, at times, during the late morning and afternoon hours. Within this convection, reductions to MVFR or IFR are expected. Winds will generally be light through the period, with brief higher gusts in any thunderstorms. There is a potential for some LLWS in the eastern sites with winds just off the sfc from the south to southeast at up to 40 kts during the first few hours of the period.
