WET MONTH

May has opened with measurable rainfall each day totaling 1.67".  We will finally get some dry time after a few spotty showers diminish Thursday evening.   The western flank of a low pressure anchored over the eastern US is still generating some instability combined with the heating of the day.  Showers in the area are expected to wither away after sunset.

CHILLY STRETCH ENDING

Early morning low temps reach the upper 30s Thursday morning at Peru, Crawfordsville and New Castle.  With clearing overnight there will likely be more wide-spread 30s to open the day Friday.

Friday morning temps could dip into the 30s again around sunrise

While May has been cool the first 4 of 5 days and wet, a much milder day is coming Friday.  The warming will continue into Saturday when stronger southwest winds develop and push temperatures to the 80° mark.

MORE RAIN COMING

We don't need it, spring 2016's rainfall surplus is now 3.57" and ranks among the wettest 8% on record and number 12 all-time.  Dry time for Friday and much of Saturday will be welcome.  To date it is the wettest open to a May in 14 years

A approaching cold front will settle into the northern half of the state bringing showers and t-storms to life by later in the afternoon and early evening.  Currently storms are not expected to be severe.  Rainfall coverage at this distance looks to reach 35% coverage.

A wind shift Saturday night will spell an end to the warmth.  We are forecasting a much cooler brand of air for Mother's Day on Sunday.  Temperatures are forecast to slide back into the low to middle 60s with light rain or showers diminishing by noon.
