Ugh. What a morning. Bands of steady rain have shifted from west to east. Rain will fall at varying intensity through the day. Sometimes the rain will fall at a steady clip with occasional downpours. Heavy rain will mix down some gusty winds from midday into the afternoon down to the ground where winds may gust to 40 mph especially at the coast from the Southeast. One batch of rain moving through this morning along with a low tracking into New York City with an approaching warm front for the south coast. Batches of showers will continue to be directed up into eastern MA for the rest of the day. With cool onshore SE winds…expect highs to remain in the lwr 60′s with a bit warmer temps inland in the mid 60′s where it will be drier this afternoon in the mid 60′s nearing 70 in spots.
A Flood watch is up Saturday afternoon through Sunday morning for heavier rain to fall in NH, ME and NE MA where rainfall will be around 2-4″…with heavier amounts in ME where the storm will stall off the coast and direct pockets of heavier rain into the region tonight through tomorrow. Rainfall estimates of 4-7″ of rain are possible in ME as a low stalls off the coast. A widespread 1-3″rainfall is likely for most, lesser amounts on the Cape.
The combination of persistent onshore winds, rough surf, high astronomical tides has the National Weather service posting a Coastal Flood Advisory tonight through Sunday. Click the link to see when your town has the best chance of seeing some minor coastal flooding.
A steady plume of moisture is being directed up the coast thanks to a trough in place across the eastern half of the US. This trough was making an eastward movement…but will begin to stall as an upper level low from the Great Lakes begins to dig in. This will really slow the whole weather pattern down and make for a pretty rough week of weather over all if you are looking for that beautiful summer like weather. The upper low will cross over New England Monday and sit over Nova Scotia Tuesday where it will sit through the midweek. Pieces of energy will pile into the trough which could help to keep us unsettled through the end of the week with periodic on and off showers.
Now let’s get back to the surface! With an upper low moving over us, a surface low will be stalled off the coast to start the week. Cool NE winds will lock in low level moisture and clouds with periodic showers and drizzle with temps remaining in the 50′s. Hard to imagine weather being any worse for June. Monday looks showery cool raw in the mid 50′s. While Tuesday..lingering drizzle with cool onshore winds will keep temps in the 50′s near 60.
The middle to end of the week has a bit of uncertainty we will have to watch. Another low will track south of New England in the Wed-Friday timeframe. If this lows stays far enough away…clouds will begin to break, temps will start to warm near 70 with a chance of a few pop up PM showers or thunderstorm. If this low tracks closer like the 06 Z GFS shows…well…all bets are off. We would be locked in the clouds for the rest of the week with the cool raw NE winds persisting as well as the periodic showers and temps in the 50′s to end the week.
This is something that does bare watching…but for the sake of sanity I leaned towards a slight warm up and slight improvement for the end of the week…still the pop up shower or thunderstorm will be possible. This week is not going to be fun. We are ready to move on into summer, yet mother nature has put on the breaks…more typical for something in April
