Wet Start To Work Week

By · July 21, 2013 at 7:26 pm

Rainy night ahead as an upper disturbance moves across the Ohio River Valley.  Best chances for rain and thunder will be after midnight, and latest model data suggests the Monday morning commute will be soggy.

As the upper disturbance swings east, and away from central Indiana, rain becomes scattered by midday.  Temperatures will struggle to hit 80° under a thick overcast.

However, areas that do see some sun will quickly warm into the mid/upper 80s.  But for now I think overcast wins out.  Despite being cooler than the heat streak last week…dewpoints will remain around/above 70° which keeps the air very uncomfortable.

The tropical air mass supports the notion that most locations pick up a .25″ to .75″ rainfall… but also puts locally higher amounts into the play the next 24-36 hours.

Rain chances remain in play Tuesday with an approaching cold front.  This front may have enough northwesterly push to bring some relief to the “sweaty stuff” we’ve endured for over a week now.

By Wednesday afternoon the Muggy Meter may actually drop into the comfortable range (dewpoints below 60°) and set the stage for a nice stretch of days to end the week.

Take your pick between Wednesday, Thursday, or Friday for best day of the week.  A developing upper level trough over the Great Lakes next weekend brings a return of rain “chances”.  Difficult to determine how much coverage at this time.  Stay tuned for updates as we approach Brickyard 400 weekend.  Thanks for reading the blog – Sean Ash
