| Area Forecast Discussion National Weather Service Gray ME 712am EDT Monday May 25 2026 .WHAT HAS CHANGED... No significant changes with this forecast update. .KEY MESSAGES... 1. Wet weather continues through midday to early afternoon. Much warmer with a chance of showers late Tuesday. 2. A fairly unsettled but 2nd half of the week is expected, with cooler temperatures and scattered showers likely. The weekend continues to look unsettled as well. KEY MESSAGE 1 DESCRIPTION... As opposed to the light rain Sunday afternoon and evening, rainfall rates through this morning will be more convective and moderate rates expected. Very early this morning as warm advection is strongest, there will be some elevated instability developing. Up to a couple hundred J/kg CAPE is forecast, so I believe that briefly heavy rainfall rates are possible. As a result, Quantitative Precipitation Forecast has bumped up a bit on modeling. HREF guidance now has a mean Quantitative Precipitation Forecast thru this evening of 1 to 1.5 inches. The max Quantitative Precipitation Forecast in that time is not much higher, so it would appear CAM guidance is all fairly consistent with a good slug of rainfall. Currently forecasts also have this moving rather quickly thru the area, wrapping up by midday in the west and early afternoon farther east. Things will turn much warmer by Tue. A return to widespread 70s and 80s is likely ahead of the next shortwave trough. That is forecast to arrive late across the region, bringing another chance of showers and thunderstorms. Right now this is mainly a threat for the northern half of the forecast area, but we will have to watch the timing on that. If the front can speed up closer to peak heating, forecast soundings indicate some skinny CAPE, good mid level dry air, and strong mid level winds. Some of those storms could end up bringing some gusty winds. KEY MESSAGE 2 DESCRIPTION... Tuesday night a short wave trough will move in from the northwest with increasing chances for showers in the north with isolated thunder not totally out of the question. Wednesday will be a bit cooler but still pretty warm. Heigheights will continue to fall on Wednesday and this will likely aid in scattered showers but it will not a washout by any means. Various sources of guidance begin to diverge with respect to the upper air pattern over Quebec on Thursday. Most ensemble guidance shows upper level low pressure diving into New England sometime between later Thursday and Saturday. This will likely portend to unsettled weather. However, timing and amplitude has to come into better agreement for us to have more confidence in the late week and weekend forecast which could be wet at times. Marine SCA (Small Craft Advisory) remains in effect for seas building to 5 or 6 feet on the coastal waters. Winds may briefly gust to near 25 kt, but overall expect those to remain below SCA (Small Craft Advisory) thresholds. Some areas of fog will be possible thru midday before winds shift to offshore and clear out the low level moisture. Winds and seas will diminish tonight. Small craft conditions are not currently anticipated Tuesday night through Friday. NOAA Gray/Portland ME Office - Watches - Warnings - Advisories ME...None. NH...None. Marine Small Craft Advisory until 8am EDT Tuesday for ANZ150-152-154. |
