Monday May 1st 6:25am... Welcome to the month of May.. A ridge of high pressure oriented N-S is current;y located across the Maritimes and will drift away to the east today, meanwhile clouds have already invaded the region ahead of a warm front which extends eastward from a low pressure system located in the American mid west. The front currently extends into the Cape Cod area and is expected to lie east-west through NB by this evening then north of the island tomorrow, thus a warm muggy wet day in store for PEI on Tuesday in the warm sector. A secondary low pressure system will develop tomorrow morning in central Maine tracking through northern NB late tomorrow night into Wednesday morning. This will also drag a cold front across the region bringing an end to the warm muggy weather. A secondary cold front sweeps across the island later Wednesday bringing in a re-enforcing shot of cold air for Thursday. High pressure approaches on Thursday cresting over the region on Friday morning. The weekend continues to look wet as a strong low pressure system moves through the Maritimes.
Precipitation.. Rain has already moved into southwestern NS/NB this morning and will slowly move across PEI later today tapering to showers tomorrow afternoon. Showers then possible into Wednesday and Thursday as a couple of cold fronts swing through. Friday looks dry bat this point then rain redevelops on Saturday with the approach of the next low pressure system on Saturday. Rainfall amounts in the 15-20 mm range expected in the initial burst of rain tonight into noon tomorrow.
Temperatures.. Remaining slightly below normal today then warm and muggy tomorrow then cooling off back to normal for Wednesday then slightly below normal for Thursday. Temps rebound back to normal on Friday then another cool Saturday.
Wind.. Very light south winds today increasing to brisk southerlies tonight into tomorrow becoming light-brisk SW on Wednesday further shifting to W-NW for Thursday. Very light winds on Friday as the high crests over the island then increasing SE on Saturday.
Thunderstorms.. Can’t rule out a rumble of thunder beginning tonight and lasting through Wednesday evening.
Hazards.. Rain at times heavy beginning later this afternoon means water ponding on roads.
