Weekly Outlook: June 8-14, 2020

Heat and humidity will gradually be increasing over the next few days, which means it actually will feel like June.

The first half of the week is a fairly straightforward forecast. High pressure will slide offshore, with generally dry weather through Wednesday. Temperatures and humidity levels will gradually increase thanks to southwesterly flow around the high pressure area.

The week starts off with very low dewpoints, but they’ll gradually rise, especially by Wednesday and Thursday. Loop provided by Pivotal Weather.

By late Wednesday, things start to get a little more complicated. A strong low pressure sure, fueled by whatever is left of “Cristobal”, will be moving across the Great Lakes and into Ontario. It will send a warm front across the region, leading to an increase in humidity levels. The low will move up towards Hudson Bay on Thursday, dragging a cold front into the Northeast. Ahead of that front, it’ll likely be fairly breezy, but also warm and humid, with the front triggering some showers and thunderstorms. There is some disagreement among the models as to when the cold front moves through the region, but right now, we’re leaning towards Thursday night.

High pressure builds in behind the front on Friday with drier conditions. Next weekend is highly uncertain at this point. An upper-level low pressure system may drift across the Northeast, which would result in some additional clouds and cooler conditions, as well as the chance for a few showers. Some models are more pessimistic than others, but given the fact that it’s been dry lately, we’re going to lean away from the models that are showing more widespread rainfall. There’s an old adage we learned a while ago that holds true with forecasting rainfall – “When in drought, leave it out.” We’re going to go with that.
