WEATHER BLOG: Dry Air In Place

We have a couple of weak low pressure centers on the map Saturday morning, one west of the mountains in West Virginia and one down near the coast of the Carolinas, but dry air across the 95 corridor is dominating our forecast and limiting any accumulating precipitation. The systems have not fused together, so west of the mountains low pressure will weaken and take a little enhanced area of snow well north across Pa. into N.Y. and the coastal storm will start to deepen Saturday morning and track northeastward to south and east of Long Island Saturday evening, then away.

Doesn’t look like the coastal storm deepens quickly enough to bring us heavy precipitation and a look at radar shows the rain and snow we have from this low will be spotty and mostly light. We do expect the precipitation to fill in though for a time in the morning into early afternoon. The snow/rain should be gone by mid-afternoon.

The wind will be brisk Saturday night behind the departing low and we clear out quickly, at least partially with that west to northwest wind. A windy day Sunday with more sun than clouds. The wind will slacken some Sunday night and we start Monday with some sunshine. However, a trough coming into the Southwest this weekend will come northeastward at the same time a cold front approaches from the northwest.
