Saturday The Better Weekend Day Rain Sunday Halloween Looks Wet
Let’s get the the weekend underway and we have dry air and high pressure in upstate NY and New England that has build southward. Clouds have thinned out and we begin the day with sunshine from Eastern Pennsylvania to Southern New England. However there is a warm front setting up to our sotuh across Southern Virginia and we are seeing clouds north of there to PA/SNJ westward. For the most part today will be dry and it will be the better of the two weekend days. Most highs today will be in the upper 50s and lower 60s thanks to the onshore flow though it will be a bit warmer south and west of Philadelphia into MD & Va..maybe low to mid 60s in these areas.
The regional radar is showing some rain moving across West Virginia and into Northern Virginia which is just north of the warm front. We may see some of those echos show up on the local radars later today but they should be mostly aloft and mainly to the west and southwest with no serious implications for the vast majority of Eastern Pennsylvania to Southern New England.
LOCAL RADAR NEW YORK CITY
Low pressure that for a short time yesterday including Tropical Storm Olga in the Western Gulf of Mexico is moving northward and producing heavy rains in the Lower Mississippi Valley northeast into the Ohio Valley. The rain shield looks rather solid and it will move eastward overnight. Rain arrives Sunday morning from west to east and it looks like it rains rather hard into Sunday afternoon.
The loop above is the GFS model from 1am Sunday to 1am Monday. It looks like parts of our area get into some heavy rain later Sunday morning into Sunday afternoon. The rain moves out between 2pm and 8pm and then weather conditions improve after that. This could be a set up for an inch to an inch and a half of rain in some areas.
On to next week and the pattern remains active. It appears that we should see seasonal temperatures in the 60s Monday through Wednesday but we may struggle around cloud cover and occasional periods where we will be dealing with a bit of an onshore flow. I would describe it as clouds mixed with some sunshine for Monday and Tuesday and perhaps more clouds on Wednesday as we start to see the next storm system develop in the Southern Plains/Texas and take aim for the Great Lakes on Thursday Halloween.
Weather models have been having trouble zeroing in on the end of next week but they seem to be coming closer now with the idea of another storm system though the timing is still a bit of an issue. This suggests rain on Thursday Halloween and then it turns dry and colder behind it for Friday into next weekend. i think there could be one more system to deal with next Sunday into Monday but we have two ahead of that one to deal with. Enjoy today as it is the better of the two weekend days for sure.
