KEY MESSAGES

- Chance for light rain (20-40%) Saturday night into Sunday.

- Chances for more widespread precipitation increase early next week, but still low confidence in the details.

DISCUSSION

Issued at 203 PM EDT Fri May 1 2026

Cyclonic flow and cold air aloft has caused scattered instability rain/snow showers across the region this afternoon per satellite and radar imagery. This activity should dissipate this evening with the loss of daytime heating and drier air advecting into the region as skies become mostly clear. Mostly clear skies and light winds will allow temperatures to dip into the low 20s if not the upper teens in interior locations tonight into Saturday morning.

Dry weather persists for much of the coming weekend, with high temperatures rebounding closer to normal values in the 50s on Sunday. Min RHs on Saturday may flirt below 25% across the interior west and central, but no fire weather risk is expected given recent cool weather and forecasted light winds generally below 15 kts. A clipper system will bring the chance (20-40%) for light rain Saturday night into Sunday.

More widespread precip chances return early next week as medium to long range model guidance continues to hone in on a series of shortwaves rotating around the eastern Canadian trough. Cooler than normal temperatures are expected through the rest of the forecast period and potentially further into the first half of May as captured by the latest CPC 8-14 day and 3-4 week outlooks.

AVIATION /18Z TAFS THROUGH 18Z SATURDAY/

Issued at 1247 PM EDT Fri May 1 2026

Mostly cloudy skies with VFR/MVFR conditions are expected this afternoon with some snow showers at times, mainly affecting KSAW. Skies should then become mostly clear and VFR this evening with the loss of daytime heating. N-NW winds of 10-20 knots are expected this afternoon, then become light and variable after 00Z Sat thru the end of the TAF period.

MARINE

Issued at 203 PM EDT Fri May 1 2026

Quiet weather persists through Saturday as gusts remain below 20 kts and wave heights stay around 1-2 ft. A clipper system will cause wind gusts to rise to around 20 knots Saturday night into Sunday with waves 1-3 ft. An approaching system may bring slightly more unsettled conditions back to the region by Monday, with wind gusts reaching 25 kts; however, long range probabilities for gusts >25 kts still remain below 30% into early next week.
