Weather Blog: Storms bring lower humidity this week
We've already seen quite a few lighter showers develop in WAVE Country this morning from a remnant MCV (Mesoscale Convective Vortex) that moved in from Missouri and Illinois. This is essentially the mostly-dead broad circulation from storms that happened well out to our west last night. This feature will likely spark additional storms in places east of I-65 this morning and into early this afternoon.
Once this feature exits after lunchtime we'll see a break in the storms and rain, even giving way to some sunshine at times. The added sunshine will reinvigorate the atmosphere for more of a scattered storm scenario by late this afternoon into early this evening. Some of those storms that form could be strong with heavy rain and gusty winds, but the severe weather threat today is very, very low. The storms fade tonight, leaving us with mostly cloudy skies and a muggy overnight period.
While there's a small storm chance in Southern Kentucky on Tuesday, for 90% of us this will be a dry day. Wednesday is EASILY the pick of the week as lower humidity air arrives from Canada. While temperatures will still be in the mid 80s during the afternoon, the lower humidity will make it much more bearable to be outside, especially in the morning and evening. Enjoy it while you can since changes are afoot again.
Friday is when the humidity ramps back up, and consequently is when our next major storm chance arrives. We'll be on the leading edge of a major trough arriving from the west that day, one that is definitely not common for this time of year. Fast winds in the mid levels of the atmosphere will be an ingredient that may lead to strong to severe storms Friday afternoon into Friday night, depending on the timing of the cold front associated with this system. It's too early to speculate more than this at the moment since the fine points of this system need to be nailed down more as we head through time.
Wash, rinse, and repeat. Yet another blast of lower humidity air arrives behind Friday's system, making for a nice end to the weekend and start to next week. The weekend won't be completely dry since the aforementioned trough may be slow to exit, but a washout is definitely not in the cards!
