Low pressure moves in, doesn’t plan to leave

A pesky area of low pressure will move into the region and stall out, keeping our weather unsettled this week. Click image to enlarge.

Like a bad roommate, low pressure will take up residence in our area this week, annoy us with more cool, dismal weather and simply refuse to leave.This low is located over Lake Superior this morning and will actually benefit us a little bit today as some more seasonable temperatures push into the Finger Lakes ahead of the low. There will be a few showers to dodge, especially later in the day, but temperatures should climb into the mid and upper 50s, which is exactly where we should be for late October. Temperatures already started rising slightly overnight, and areas just to the west are starting the day in the upper 40s and low 50s.

As the low drops across Lake Huron, we should see more shower activity move into the Finger Lakes tonight. The low will then slowly track across our area, keeping showers in the forecast for much of Tuesday. With the clouds and showers, temperatures will be cooler tomorrow with highs in the low and mid 50s.

It looks as if we may get a break from this system on Wednesday as it moves off the Mid-Atlantic coast. There will still be a chance for stray shower here and there, but for the most part, it looks like a dry day. Temperatures will be slightly below average since the low will be to our east.

The low will then slowly drift north towards Long Island, where it will spend much of Thursday. As it sit over the relatively warm waters, it will feed off of the temperature difference between the water and land and the low will strengthen. As it does so, it will probably throw precipitation back at us for a rainy Thursday and showery Friday.

Finally, by the weekend, our pesky weather roommate should pack its bags and head out to sea, leaving us with a fair weekend.
