Highly-Variable Rainfall Today…….Patchy Dense Fog Developing Tonight……Severe Weather Information

May 17th, 2013 at 9:58 pm by under Chad's WLFI Weather Blog

Rainfall varied greatly today with many places seeing little or nothing, but others getting a torrential 1.50″.  Slightly better dynamics helped storms organize a more today into a bit of a broken line with several pulsey multi-cellular storms.

One hail report was received & that was CoCo Puff-sized hail in Miami County, 6 miles southeast of Peru.  However, there were clear signs of hail in northeast Benton County, northwest Carroll & briefly in western Clinton (pea to penny size in all cases).  Measured t’storm gusts at NWS & WLFI weather stations from t’storms were 23-40 mph with couple cells showing potential 40-50 mph gusts.  However, there were no weather stations at these locations, nor did I receive any wind reports from these locations in Miami & Benton counties.

A few isolated showers/t’showers are possible tonight (15-20%), otherwise skies will be partly to mostly cloudy with patchy dense fog developing.

With lack of dynamics/forcing Saturday & Sunday, I only expect a few isolated to widely-scattered showers & t’storms (25%).

After highs of 80-83 Saturday, highs of 84-88 are likely Sunday.

It looks like 3 rounds of showers & t’storms Monday afternoon-evening to Tuesday night (lingering showers even to Wednesday morning).

Wave #1 will likely pass Monday afternoon-evening as scattered storms with scattered severe threat.  Wave #2 will pass Tuesday afternoon with main severe threat.  Wave #3 of showers & storms will pass Tuesday evening-night.  Right now severe threat looks less with that round, but we will watch.

Late this week to Wednesday morning, a solid 1-3″ of total rainfall is likely viewing area-wide.

After Wednesday, current data points towards an extended period of pleasant weather.  Memorial Day look dry & mostly sunny right now with highs in the upper 70s.  We will watch it, as tweaks are possible to that forecast between now & then.

Update

May 17th, 2013 at 6:12 pm by under Chad's WLFI Weather Blog

Semi-organized band of showers/t’storms continues to progess northward.  The pulsey intensity has tended to wane, but the t’storms are producing some potential rainfall.

Wind gusts up to 30 mph are possible with the t’storms.  Isolated hail threat has diminished.

I will keep a isolated showers/t’storms in the forecast for tonight, given recent new development near Greencastle, which is moving northward.  However, overnight coverage will run just 20%.

Small Hail Possible Western/Northwestern Carroll County

May 17th, 2013 at 5:34 pm by under Chad's WLFI Weather Blog

Likely small hailer is moving through areas around Delphi, moving north.  Again, storms are pulsey, so hail threat may not last very long.  Gust to 45 mph is also possible.

These are headed for Monticello, Yeoman, Chalmers & Reynolds.

Torrential rainfall will accompany the storms with a quick 1.50″ possible in places.

Brief Pea Hail Possible In Northwest Clinton County

Brief pea hail appears to be developing in storm west of Frankfort moving toward Rossville.  These storms are pulsey, so this hail potential may not last too long.

Miami County Storm Weakening

May 17th, 2013 at 4:28 pm by under Chad's WLFI Weather Blog

Storm is weakening & drifting northwestward.  It is likely not producing any more hail or wind, but quite a downpour of rain.

Pulsey scattered showers & t’storms continue to drift north & northwestward across the viewing area.  Random pulse of a storm or two to strong-severe limits is still possible.

Hail to 0.75″ Diameter Possible Near Peru

May 17th, 2013 at 4:13 pm by under Chad's WLFI Weather Blog

Miami County storm is approaching severe limits with high likelihood of 0.75″ diameter hail & wind gusts of 40-50 mph.  These storms tend to be pulsey, so it may not maintain such strength long, however.

Wind just gusted to 35 mph at Attica Golf Course, according to Tyler Snider.  Wind gust of 37 mph measured at Attica.

Scattered t’storms will continue to develop this afternoon through evening with the potential of an isolated severe t’storm.  Currently, scattered t’storms are popping & moving northward.  Some will pop right overhead over the next 1-2 hours.
