Smoke Annoying Vermont, And Much Of Northern U.S. Storms/Rain Lurk In New England Too

A bit of another severe risk. Level 2 out of 5 risk of
damaging winds in the Northeast Kingdom and in
northern New Hampshire and half of Maine.
Northwest and central Vermont are at a level 1
out of  5 risk. This won't be as serious as the
destructive microbursts in south central
Vermont early yesterday morning. 

The smoke is back, especially in southern Vermont. Big wildfires in Ontario and northern Minnesota is causing most of the trouble. 

Smoke will be a problem for the rest of the summer, probably. Rain might tamp down the Ontario fires Friday and Friday night, and that might temporarily help. 

All this pollution makes the overall weather forecast a little harder, both for understanding when the smoke will be thickest and how that will affect overall weather. 

Later yesterday, the thick smoke got suppressed south to near the Massachusetts border and points south and west. Northern Vermont got a temporary break. 

TODAY

Unfortunately, satellite imagery was down this morning so I don't have a full picture of what's going on with the smoke. Just a general idea.

However, we know the smoke moved back north overnight, but it's still thickest in southern Vermont. An air quality alert is in effect until 11 p.m. tonight for all of Vermont except the far north. It's part of a broad air quality alert zone extending from Minnesota to Massachusetts. 

Another cold front is going to temporarily squash the smoke southward this afternoon. The cold front has already set off some needed showers in northwest Vermont, an area that could use some rain  Unfortunately, there is a risk of a few strong or even severe storms today. 

It's been a stormy summer. 

The weather set up is similar to Tuesday, when we were expecting a big outbreak of severe storms. The main difference is that it's much less humid than it was on Tuesday. So there's less potential fuel for storms

This time, the smoke is somewhat lighter in northern Vermont. Despite the lower humidity, the lack of smoke means there could be a few strong or borderline severe storms. Especially as a new cold front accompanied by a weather disturbance approaches us from Quebec.

This will not be a big storm outbreak.  Some of us won't see any showers or storms at all. NOAA's Storm Prediction Center has much of Vermont under a marginal risk of severe storms, a level one out of five risk. 

The Northeast Kingdom, northern New Hampshire and southern Maine have a higher risk, a level two out of five alert level for severe storms. Far southern Vermont is outside the risk zone. 

Again, this won't be anything as serious as those destructive microbursts that hit towns like Shoreham, Whiting, the north end of Lake Bomoseen, Shrewsbury, Windsor and other spots late Tuesday and early Wednesday.  

Just keep an eye to the sky and get into a building if a storm is approaching. A couple spots could have some damaging wind gusts. The storms should be around early to mid afternoon north, and mid to late afternoon south. Though southern Vermont should see few if any showers and storms 

The good news is the cold front will temporarily disperse the smoke later today, especially north. 

FRIDAY

Should be a nice day. After a comfortable night tonight, we should have a sunshine, low humidity with highs in the70s to low 80s. It looks like we should still have some wildfire smoke hanging around. It's hard to say for sure, but current forecasts suggest the smoke might be worse south and west of Interstate 89.

WEEKEND

Saturday looks rather rainy. Which is good, as several places in Vermont have been cheated as thunderstorms have missed them this month. Northwest Vermont seems particularly dry. The first half of July in Burlington had 1.37 inches less rain than normal.  

You might be able to squeeze in some outdoor activity during the first half of Saturday, since the bulk of the rain should come through later in the afternoon and evening. Early forecasts call for an inch of rain in northern Vermont, with a little less than that across the south.  

It looks like Sunday will clear up in the afternoon. It also looks like it might be the coolest day we've had since maybe the third week in June. Highs should stay mainly in the 70s.

The weather pattern has changed. No promises, but it appears the second half of July might be cooler than the first half of the month.
