Today’s weather did all that it could to bump yesterday’s weather off the top ten list. One may argue that it was a little too warm and with temps between 80-85 for most, one might have an argument. Boston touched 82 degrees which was eight degrees above normal and with SW winds still kicking…Friday will be another warm one with similar numbers in the 80-85 degree range except for SE Mass where 70s will be more common.
A coldfront is slicing thru the Midwest and there is a noticeable temp drop behind it. This front will pass through New England Saturday morning. Along the front I expect only a skinny line of showers to be present and therefore rain amounts will be hardly measurable. There is a chance that rain gauges only pick up a trace of rain and if so our streak of dry days could stretch as long as nine days before it undoubtedly ends early next week. As for the rest of the weekend behind the front, expect more Autumn-like conditions with chilly temps in the morning and evening but daytime highs under bright sunshine in the lower 70s…what a weekend!
Early next week, the pattern will become amplified as a stalling shortwave coming down from the Prairies of Canada will morph into a digging longwave trough in the Central and Eastern US. This will set-up a very moist fetch coming out of the Deep South. Tropical moisture will surge ahead of a coldfront and leading edge of the trough. Mid-level energy will induce surface cyclogenesis on the front as it works through the Northeast. The end result will be a slow moving windswept rainstorm capable of gusty winds and rain amounts over an inch. The timing appears to be Tuesday with lingering showers into Wednesday of next week.
