Marine Weather and Tide Forecast for McCleary, WA

SHORT TERM /TONIGHT THROUGH WEDNESDAY/
Recent radar imagery shows scattered shower cover pushing from the south with a weak front crossing the area. An upper level low spinning offshore is aiding in shower development across the area this afternoon.
Latest hi- resolution guidance is depicting shower coverage generally moving northward across the area into the evening. There is a chance of convective showers through this evening, where a rumble of thunder and perhaps a lightning strike or two cannot be ruled out. Model guidance is seeing very minimal instability values, so the chance of thunder and lightning is low, but it is there. Temperatures this afternoon mainly hovering in the low to mid 60s.

The aforementioned upper level low will continue to drift southward and bring some wrap around moisture into Monday, keeping showers in the forecast. Weak upper level ridging looks to build into Tuesday and will be the primary influence on the weather through Wednesday, keeping the area mostly dry but a few showers are still possible in the higher terrains such as the Cascades during that time. Temperatures largely remaining the same.

LONG TERM /THURSDAY THROUGH SUNDAY/
Ensembles are hinting at more upper level troughing in the long term period, which would bring more unsettled and showery weather into the weekend.
Deterministic models seem to be split on the strength of multiple frontal systems at this time, but overall consensus looks like more troughiness and showery weather through the long term.
