Weekly #AGwx And #Severe Weather Outlook…

I. Recent wet pattern remains intact.

II. Persistent hot, muggy regime takes us into the holiday weekend.

Temperatures will run above to well-above normal from the Plains into the Great Lakes and Northeast this week. The Rockies and points west can expect unusually chilly conditions.
Wetter than normal conditions are expected across the southwestern OH Valley into the TN Valley this week, along with the northern Rockies and New England.
We forecast 7-day rainfall totals for central IN to fall within the 1.75″ to 2.50″ range with locally heavier amounts.
In this pattern it won’t take much to have one or two storms pulse to severe levels, but widespread severe storms aren’t expected, locally. The biggest concern from any stronger storm that does form will be centered around damaging straight line winds.

Forecast Period: 06.28.20 through 07.05.20

A stationary frontal boundary will remain draped across the region until Tuesday night before getting a slight “nudge” off to the southwest Wednesday. The warm and humid pattern in place today will remain locked into the area straight through the holiday weekend (with a small break in humidity midweek). Periods of hefty thunderstorms can be expected- most numerous during the afternoon and evening hours. With such high moisture content in the air, locally heavy rainfall is expected at times. This “rinse and repeat” forecast will begin to change up by the holiday weekend as ridging builds overhead. While this won’t help us with the heat or humidity, this will reduce rain chances. Instead of scattered to numerous coverage, we’ll be talking about isolated coverage for the holiday weekend, itself. Most will stay dry. By this time frame, we’ll monitor the goings on to our south as a cut off low keeps the TN Valley into the Southeast region unsettled with more widespread storm coverage for the holiday weekend.
