Detailed Discussion
March sunshine was quite welcomed yesterday, even if temperatures didn’t live up to their average readings in the 30s and low 40s in early March, mostly in the 20s. High pressure that brought the late-season shot of the arctic crested over us in the afternoon, slowly drifting into the Atlantic overnight. This sets up a series of changes, though it might not be apparent from a look at your sky or thermometer. The clear skies northeast have again sent readings to near or below zero, while south winds and some clouds west and south have lifted readings from the single numbers and into the teens. But the broader view shows the exiting high responsible for both the clear skies northeast, and the clouds and milder air approaching. Expect those clouds to expand north on this Town Meeting Day in Vermont, leading to some wet snow, or some valley rain near midday in Bennington, spreading northeast to about Rt. 2 and the Adirondacks by nightfall, becoming all snow, not reaching much farther north than the Quebec border. Enough snow, ranging from 1 to 4 inches north to Rt. 2, and locally up to 6 inches in central NH, will result in some winter driving conditions toward the end of town meeting south, continuing overnight, so the National Weather Service decided to place the southern-most counties of VT into MA, east through central NH under Winter Weather Advisories. A minor storm sliding east along a warm front stalled through the Ohio Valley, and lifting north to the southern New England coast will guide the snow fairly quickly east overnight, tapering off by midnight west of the Green Mountains, and before daylight in NH. Some clearing may develop later at night, part of some drier, milder air arriving Wednesday with increasing sunshine, and temperatures climbing into the the 40s, maybe nudging 50 in the warmer valleys south. The same front stalled to our south gives another weather system an opportunity to form later this week near Missouri, while a wedge of high pressure establishes itself to our north. This could make for some messy, changeable weather late Thursday into Friday. After a generally clear night Wednesday night, clouds again increase from the south Thursday, along with another mild day, in the 40s. Some rain begins to lift north with the front late Thursday into Thursday night, however, enough cold air north and east of I-89 could mean a wintry mix of snow, sleet, and freezing rain. A difference of only a few degrees could have a significant impact in the types and timing of the precipitation, so confidence in the details is still low. A generally mild west and southwest airflow follows into the weekend, with some episodes of thawing rain or showers. This bears watching as the rain, with melting snow, and thawing temperatures could lead to river rises, and an increasing potential for ice breaking up, leading to ice jams and ice jam flooding.
