Beautiful Tuesday Sunshine Dry Air Drains Southward
Sometimes having a tropical or non tropical storm nearby is a good thing if you are in the right spot. Right now the Northeast south to Delaware and Northern Maryland seem to be in that ideal spot sandwiched in between soon to be Post Tropical Storm Arthur to the southeast and an upper low to the west and south. Dry air from New England is draining southward creating sunshine on a gusty northeast wind. This will be nice day with highs mostly in the 60s though it will be a little cooler along the shore.
Regional radar is showing heavy rains across North Carolina to Western Virginia northwest into West Virginia and Ohio. This is due to the upper low that is dropping southward into Tennessee. With this upper low remaining so far west the impact here will be minimal. Note the rain areas are moving northwestward which means they never get even close to us over the next few days.
What was a worry some outlook last week has turned into something for more pleasant for the Northeast and our area at least pretty much through the rest of the week. An upper highs is keeping things dry while an upper low causes moisture to flow from the Carolains to the Ohio Valley instead the the usual track northeastward. With the low in that position in Central Kentucky and Tennessee and blocked by the upper high over the Great Lakes into the Northern MIddle Atlantic, the rain can’t come here. We stay nice and no worse than partly sunny for Wednesday and Thursday. It could even go mostly sunny especially from NY north and northeast. Highs will be in the 60s Wednesday and in the 60s to near 70 on Thursday. Cooler temperatures are likely along the immediate shore.
The upper high won’t last forever and it finally breaks down on Friday. Rain from the upper low finally starts moving northeastward with rain moving into Southern Pennsylvania and Southern New Jersey during Friday afternoon and then reaching areas north and east of NYC to Southern New England late in the afternoon or evening. Highs Friday will be in the 60s. The Memorial Day holiday weekend is a tough one because while rain will probably move out during Friday night or early Saturday there may be cloud issues for the rest of Saturday and only slow improvement for Sunday and Monday. Remnants of the upper low will hang around the Northeast into at least Sunday. After rain moves out Saturday morning (except for perhaps Long Island and Southern New England), we shouldn’t see much if any rain for Sunday and Monday. Hopefully there is enough dry air around to allow for some sunshine. This is a puzzle for forecasters to decipher in the coming days.
