    Large low pressure cold front will slowly lumber across the Great Lakes, keeping the threat of severe weather in the forecast through the rest of the work week. Cooler air on the backside will provide some relief from opressive heat in time for the weekend. Things really dry out by Sunday & into next week.

    We'll stay in the warm sector of that cold front over the next few days. Hot and humid conditions persist across much of the eastern US as lots of warm moist air lifts north ahead of the frontal boundary. We'll see a bit more sunshine today than yesterday. Highs will again top out around 90. Scattered thunderstorms will again develop by late afternoon into this evening. Any storms that crop up will be capable of producing heavy rainfall, strong winds and hail. We'll see breezy conditions with gusts into the teens tonight & over the next 48 hours.

    Low pressure cold front will continue its gradual eastward track Thursday...departing Friday. We'll keep the threat for isolated severe weather Thursday. But that threat will be waning as we finish out the work week. A nice punch of dry air will fill into the region Thursday into Friday. Dewpoints will fall back down to the 50s. Cooler temperatures will filter in on the backside of the front late Friday. This will put highs in the upper 70s Friday & into the weekend. Lows will fall into the upper 50s!

    Slight chance for thunder will still linger into Saturday afternoon and evening. Convection will be isolated but like the past few days, pop up storms could produce locally heavy rainfall, breezy conditions and hail. By Sunday, things will really dry out aloft and at the surface. Rain chances diminish to almost nil for at least the first half of next week.
