Large complex of rain & t’storms is moving in.  There have been Severe T’Storm Warnings on the line segments with it in around St. Louis & in southwestern Illinois.

Increasing low-level jet may tend to maintain it, so isolated strong-severe gust possible along & west of U.S. 231 in an otherwise run-of-the-mill summer MCS.

Multiple, evolving cluster of storms exist to our west in Iowa, Illinois, Kansas, Oklahoma & Missouri.  The tendency will be for a large complex of showers/storms to evolve in Illinois over the next several hours & affect this evening as it moves west to east.

Nonetheless, MCV from Iowa storm complex last night is pivoting through northern Indiana with still a few showers & t’showers in our northern & northwestern counties.

BELOW IS A GREAT GRAPHIC ON THE THE JUNE 12-13 SUPERCELLS & DERECHO FROM THE NATIONAL WEATHER SERVICE, NORTHERN INDIANA OFFICE. 

NOAA’s SPC released this statement:

- The event of Wednesday evening June 12th-Thursday morning June 13th can be considered a low-end derecho. While a few significant wind reports in excess of 70 mph occurred in Indiana, the lack of higher wind speeds/gusts along the entire track of the bow echo keep this event on the lower end.

- Widespread severe thunderstorms over the Midwest during the late evening, became organized into a squall line over Indiana before Midnight EDT. The line then accelerated east across Ohio, Pennsylvania and New Jersey through Thursday morning, June 13, 2013 with an average forward speed of 47 mph.

- The bow echo/derecho traveled over 400 miles in about 6 hours during its peak intensity resulting in over 100 damaging wind reports. The most significant damage appears to have occurred during the late evening across parts of Indiana.

I will have a write-up on the outbreak from our viewing area’s perspective soon.

Iowa leftovers/MCV with a few showers/t’showers is pivoting through area now.  Rain coverage is only around 20-25%, however.

New storms (multi-cell clusters) are blowing up in Iowa & western Illinois.  The trend through the after will be for all of these multi-cells, & even a few supercells, to gell into a rather large MCS or complex of rain & t’storms.

The MCS will tend to pass this evening.  Main severe threat will stay west of here, but I would not be surprised to see a few isolated strong to severe gusts make it into our area along & west of U.S. 231, though MCS will be in a weakening mode as it moves in here.

Highs today ran in the upper 70s to low 80s with low humidity.  Overall, it was another very nice day!

Cluster of storms in Iowa will move southeastward, but will weaken with approach here.  Nonetheless, a round of some scattered showers & t’storms will pass very, very late tonight-Saturday morning.  They will continue to diminish as they work east& southeastward, but may hold on long enough for some showers/t’showers in the Indianapolis area in the early afternoon.  Coverage will run around 20-30% as Central Catholic takes on Vincennes Rivet in the Class 1A State Baseball Finals.

It still looks as if a break will ensue in the afternoon after any morning rain with some dim sun developing.

Then, it appears, numerous storms to the west in Iowa, Missouri & Illinois with congeal into a rather large complex of rain/t’storms.  Main severe threat will remain in Iowa, Illinois & Missouri with a gradual weakening trend with approach into our area.  However, a few strong-severe gusts may hold on into our area on the leading edge of the complex (MCS).

We are fair game for this after 6 p.m.  Hopefully this round will slow down & arrive later (in the overnight).  This will continue to be monitored for potential tweaks.

It is another beautiful day!  After a cool start in the 50s, we are in the upper 70s to lower 80s with low humidity.

Wave of some showers & storms will pass late, late tonight-Saturday morning & exit by midday.  A few showers/t’showers may hang on in/near the Indianapolis area around 1-2 p.m., before dissipating.

Skies will then turn partly cloudy with rising temperatures & humidity while severe weather gets going to our west.  Supercells & multi-cellular clusters with hail, wind & isolated tornado threat will tend to gell into a large complex of rain/storms or an MCS.

This MCS would affect us in the evening.  Now, the MCS will be moving into an environment that is a bit less conducive to severe weather here.  However, on the leading edge of the MCS, I would not be surprised to see some gusty winds, including a few severe wind gusts.

We are fair game for this in the viewing area around 6 p.m. & after.

MCS will exit tomorrow night, but more storms are likely Sunday.  The Sunday situation is slightly blurry in terms of storm mode.  It appears, right now at least, that another MCS may affect the area as new storms form on previous MCS’ outflow boundary that curves to the northwest towards Missouri & Iowa.

New data suggests still a few showers/storms late Friday night-early Saturday.

A break is likely with sun & clouds for a good chunk of Saturday.  The afternoon looks dry, warm & increasingly humid with highs of 81-86.

It then appears an MCS (complex of rain/storms) may affect us in the evening-early overnight, rolling in from Iowa & Illinois.  Storms may produce quite a bit of severe weather over Iowa, Missouri & Illinois as they gell into that MCS with a squall line at the leading edge of it.

Although they may be in a weakening mode as they move into our area, a few severe gusts still seem to be a good bet.

That will go through, then new storms will fire Sunday, which may congeal into another round that affects late in the day with a few severe gusts.  Highs will run 84-89.

This time last year, the drought was rapidly worsening & data suggesting a significant heat wave developing down the road towards late June.  This occurred after a heat wave in May.

Yesterday, we had our first 90-degree day (of the year) at WLFI with 91.  At this time last year, we had already had 7 days at or above 90 for the year.

Many areas are much wetter for this month than we are here in West Lafayette here in 2013.  Some northwestern areas have already had 5″ of rain for the month of June so far.

It is interesting to compare what it was like at this time last year, compared to this year (in terms of moisture & temperature).

These are all of the watches & warnings issued this afternoon as of 5:30 p.m.:

Yellow:  Tornado Watches

Pink:  Severe T’Storm Watches

Orange:  Severe T’Storm Warnings

Red:  Tornado Warnings

Today & tomorrow look great, but a few showers/storms are possible late Friday night-Saturday morning.  A wave of showers/storms will then pass most likely Saturday evening.

Isolated severe weather is possible with that round in the form of a damaging gust or two.

An additional wave of showers & t’storms is likely Sunday.  These showers/storms will be occurring right on the edge of intense heat to our southwest.

Highs will run at 79 today & Friday & near 83 Saturday & Sunday.
