After lows this morning of 32-35, highs today reached 54-64, lower than projected highs of 61-67.  High at the Purdue Airport & our WLFI site was 62.

Widespread rainfall will pass tonight-tomorrow morning to midday.  Rain will tend to be heaviest in the 6 a.m.-10 a.m. time frame.

Isolated embedded t'storms are possible.

East to northeast winds will be strong with gusts to 40 mph.

Localized flooding is possible. 

Temperatures will be cold at 39-45 with wind chills 29-34 in a driving rain!  Yuck!

Rainfall decreases, then exits by afternoon.

Severe weather risk will set up just south of our area, south of the warm front.

It appears the warm front will stay south of our area with cold, strong northeast winds in the afternoon with lots of clouds.

Even tomorrow late morning, there will be a very sharp temperature gradient over the warm front!

From 40s to 70 over a short distance!

Highs tomorrow will only run 45 in the far north to 50s in the heart of the area & near 62 in the far southeast.  A bit farther sout near I-70, 69 is possible with some severe weather risk.  70s will occur in southern Indiana.

Note the severe weather risk creeping as far north as the Indianapolis area.

Believe it or not, a band of near-record late heavy, wet, gloppy snow may occur with temperatures 35-36 Chicago to South Bend.  Localized, slushy +1" accumulations are possible!  These are areas that were around 90 with near all-time earliest occurrence of 88-90 on record May 1.  For example, Milwaukee hit 88 on May 1 & had a low temperature on May 2 of just 67!

1.5-4" of rainfall is likely.  Much of the area will receive 1.5-2.5".  A couple of of +2.5" band will occur in our north & perhaps in the east-central parts of the viewing area.

Monday looks partly to mostly cloudy with highs 54-63 north to south (61 Greater Lafayette) after 36-41 (38 Greater Lafayette) in the morning.  Winds will be north 10-15 mph.

Monday night will continue to be partly to mostly cloudy with lows 36-42.  Winds will be north at 6-10 mph.

Tuesday will turn mostly sunny with highs 57-64 (63 Greater Lafayette), followed by clear & calm conditions Tuesday night resulting in patchy frost.  Lows of 34-39 are likely (37 Greater Lafayette).

Biggest change to the forecast is Wednesday-Wednesday night.  Surface high should hold strong & keep system southwest & south of our area, though we may pick up some cloudiness.

With north to northeast wind, highs of 62-69 are likely (68 Greater Lafayette).  Wednesday night should be clear with 37-46 (45 Greater Lafaeytte).

Some moisture may try to creep in Thursday, so kept 20% coverage of rainfall with clouds/sun & 62-69.

Friday looks warmer & breezy with sunshine & 70-77 with lows in the 50s.

Saturday & Sunday look windy & warm with sunshine & clouds & highs surging to the 70s then 80s & lows int he 50s, then 60s.

Some storms are possible near the warm front over the northern half of the viewing area with MARGINAL to SLIGHT RISK parameters.

Best potential of storms is later Monday with 80s & SLIGHT RISK parameters after some storms in the morning in the northern part of the viewing area.

Best potential of severe weather is around May 20 with 80s to 90s, 60s to 70s dew points, strong south-southwest winds & ENHANCED RISK type parameters for severe weather.
