Weekly Highlights:
I. Cristobal’s remnant moisture
II. Strong cold front delivers unseasonably cool close to the week
Forecast Period: 06.06.20 through 06.13.20
Though it’ll still be a warm weekend, less humid air will be welcomed with open arms. Dry conditions will prevail through the weekend and as we open up the new work week, including plentiful sunshine. All eyes through the weekend will be on the Gulf of Mexico and Tropical Storm Cristobal. Cristobal will slowly strengthen over the next 24-36 hours before making landfall as a strong tropical storm along the southeast LA coastline. While we still don’t think we’ll be directly impacted by Cristobal’s remnants (those will track through the MS Valley and into the Upper Midwest), the fetch off the Gulf Coast directly ahead of a midweek cold front will lead to better chances of rain late Tuesday into Wednesday. That aforementioned cold front will be the first of two fronts to sweep the region before week’s end. The second front that blows through Friday will usher in a fall-like airmass next weekend.
Most of our Wednesday will be rain and storm free with a very warm and tropical feel. Don’t let this lull you in to letting your guard down as storms are expected to still erupt to our north late afternoon before rumbling south into central Indiana this evening.
The biggest concern with this storm complex will be centered on the threat of damaging straight line winds as embedded lines of storms may “bow out” on their journey south this evening. Additionally, large hail will also be possible with a few of the storms. As such, the Storm Prediction Center (SPC) continues to include the heart of the state (and the Ohio Valley for that matter) in a Slight Risk of severe weather today.
A good chunk of the region can expect 0.50″ to 1″ of rain this evening with locally heavier totals.
As we look ahead to the weekend, a front will sweep through the state and usher in a much less humid air mass Saturday night into early parts of next week. Sunday and Monday mornings should feature lows back into the upper 50s for most of central Indiana. Additionally, we’ll continue to keep close eyes on Tropical Storm Cristobal in the Gulf. There’s still the potential Cristobal’s remnant moisture will get entrained with an approaching cold front the middle to latter part of next week, leading to the threat of locally heavy rain across the MS Valley and parts of the Mid West and Ohio Valley. We’ll be able to become more specific as time draws closer.
