Long Island Under Flash Flood Watch Tuesday
Thanks to Nor’easter Developing Offshore
Low pressure is moving across the Middle Mississippi Valley and will be heading east into Ohio before dying out and a secondary storm off the North Florida coast moves north northeastward up the coast bringing heavy rain and gusty winds later Monday night and Tuesday. Flash Flood Watches are posted for Tuesday. Before we get there we have tonight and Monday. We managed to stagger through today in spite of increasing clouds and one lone renegade shower that showed up on the radar this afternoon. Clouds will continue to increase tonight as a warm front comes up from the south.
SATELLITE
While the local radar is quiet this evening the regional radar is showing rain moving into Western and Central Pennsylvania. Most of that rain will pass to our north but Long Island could get into the southern edge of that rain later tonight as a warm front come up from the south. Most of the rain will be to our north shortly after daybreak.
WEATHER RADAR
Monday the warm front will be to our north and we will be in the warm sector. Look for clouds or at best changeable skies with temperatures reaching into the 70s. Thunderstorms will develop Monday evening as the low to the west weakens and the secondary coastal low takes over and begins to strengthen. Long Island lies just outside the marginal risk zone for severe weather per the Storm Prediction Center at least for now. If we wind up with more sun on Monday and higher highs it might trigger a strong thunderstorm Monday evening.
Later Monday night and all day Tuesday from off the ocean will sweep back westward. Some of the rain will be heavy and at least a couple of inches of rain are likely. Depending on whether a thunderstorm or two gets involved, local amounts could be higher. As far as winds are concerned, for now the low produce the strongest gradient over Eastern Long Island and Southeastern New England. The strongest wind gusts should occur there with gusts to gale force. Further west along the South Shore, while winds will be gusting to 30 to 40 mph at the peak, they should be manageable. As for coastal flooding thankfully the full moon was last week and we are approaching the lower point of the tide cycle. Still some minor coastal flooding seems likely at this time for high tides Tuesday into Wednesday. Rain should taper off Tuesday night but we will remain cloudy on Wednesday and possibly Thursday before the next storm heads our way with more heavy rain chances Friday.
