FNUS71 KGYX 211112 FWSGYX Spot Forecast for NAVHDA RX Project...Maine Forest Service National Weather Service Gray ME 712 AM EDT Tue Apr 21 2026 Forecast is based on ignition time of 0900 EDT on April 21. If conditions become unrepresentative...contact the National Weather Service. Please contact our office at (207) 688-3224, if you have questions or concerns with this forecast. Morning surface inversion will have mixed out by 9am with winds increasing. While this implies more gusts, winds in the low levels are relatively light. They should be enough to mix down drier air however, with RH values decreasing through the morning under full sun. A sea breeze will make its way inland from the coast this afternoon, arriving near the RX late this afternoon/early evening. This could bring a southerly wind shift and increase in winds. Gusts taper off shortly after, as surface inversion returns for tonight. Good recovery is expected tonight with increasing cloud coverage. Showers move into the region through Wednesday morning. .REST OF TODAY... Sky/weather.........Sunny (20-30 percent). CWR.................0 percent. Chance of thunder...0 percent.
