We’re about to put June into the rearview mirror.

This is going to be a quick post!

Surface chart and Radar

Today marks the last Friday in June as this active weather pattern continues.

Looking at the surface chart, we can see a couple of stationary boundaries over the region, along an area of low pressure moving into the Saint Lawerence Valley with an attached cold front sitting over western New York State extending back through northwest Pennsylvania into the Ohio Valley. There is high pressure sitting up over the Great Lakes.

Today is going to going to see seasonal temperatures with variable cloud cover.  As that area of low pressure in northern New York State drifts eastward, it will move over northern New England this evening into tonight. This will bring scattered rain showers and some thunderstorms.  The Storm Prediction Center (SPC) has placed a Marginal Risk for severe weather over Northeast New York State including the Champlain Valley, most of Vermont and New Hampshire into Maine. The main risk will be strong gusty winds, hail and some heavy downpours, the storms will be moving fairly quickly, so the flood danger is rather low. The tornado risk is very low.

Tonight we’re going to see an area of low pressure move along a boundary to our south. At the same time, we’re going to see high pressure move into New York State.  This will create a complex setup across the region for the weekend.

This area of low pressure will be tracking east across Pennsylvania Friday night into Saturday morning. The rain will move back into western Pennsylvania this evening and into Saturday morning, the rain will make it into eastern Pennsylvania tonight into the overnight rain as it heads for the Delmarva Peninsula. Saturday there will be areas of heavy rain, especially around the Masion Dixion Line and points south. The rain will be ending west to east on Saturday; things look to taper off early Saturday afternoon across the Middle Atlantic and eastern Pennsylvania. For the most part Sunday looks to be dry and quite warm and muggy, across our southern areas.  Across northern New York State, northern Vermont, northern New Hampshire into Maine, both weekend days, look to be mostly dry, but there will be chances for rain showers each day. For the rest of the region between these two features, it should be mainly dry, with only the slight chance for a rouge rain shower.

Last night I posted on the ring of fire that is going to be setting up next week, if you haven’t read it, you might find it useful to do so!

The high-pressure ridge heat dome is going to be setting up. over the Great Lakes and Ohio River Valley. This is going to trap hot and humid air under this dome. Some of this heat and humidity will make it into western parts of our region, but central New York State will be on the edge of the heat, but it will still be quite warm and humid. As this ridge builds, we’re likely to see thunderstorm complexes rotate around the dome. These could impact a large part of the Northeast into the northern Middle Atlantic.

That’s it, have a great weekend
