In the short term, high pressure will control the weather in central New York. By tomorrow morning, high pressure is forecast to be positioned over extreme northern Maine and is projected to continue to move east and set up shop near the New Brunswick and Nova Scotia boarder. This should result in a decent Tuesday as sun fades behind increasing afternoon clouds.
The clouds will be in advance of our next weather maker. This system is a strong area low pressure that is pulling out of the Texas Panhandle this evening and will move into the Ohio Valley later Tuesday. This system will bring a mix of wintry precipitation starting Tuesday night. Although we are forecasting temperatures near 40 Tuesday, by Tuesday night we will drop into the 30s. There should be a mix of snow, rain, sleet and even freezing rain around central New York. It is still a tricky forecast because the temperatures in the lower atmosphere will be close to freezing, but it appears the best chance for any accumulation of snow Tuesday night will be over higher elevations (where it will be colder)
By Wednesday morning there will actually be two areas of low pressure making up our complex weather system. One low will be back over Ohio while a second low will be near Baltimore. Maryland. This second low will become the main low and northerly winds around this low mean we will gradually cool the rest of the week. Any mix of precipitation still falling on Wednesday will change over to all snow Wednesday night and Thursday. Right now, it doesn’t look like any significant accumulations of snow will occur.
Once this storm system arrives it will be in no hurry to leave. We have unsettled conditions for the rest of the week and into the beginning of the weekend not only in central New York but also into the Northeast. You can expect plenty of clouds, below normal temperatures and some snow.
