WLFI Video Blog Entry April 12, 2013

Forecast Discussion:

With that cold front now to our east, the strong upper low located to our northwest will insure that temperatures peak well below the average high for this time of the year. As it delivers the cooler air mass from the upper Great Plains, that low will position itself over the Great lakes later this afternoon and possible supply the viewing area with a brief period of isolated rain. We’ll see some partial clearing overnight as temperatures dip near the freezing mark; expect a low of 34° in Lafayette this evening. High pressure will begin to push in from the southern Great Plains for Saturday; while we’ll see some more sunshine, temperatures will remain 9° below average. The very same high will situate itself to our east by Sunday morning ushering in warm and moist air mass from the southeast. Temperatures will jump up into the upper 60s and low 70s throughout the viewing area, but much like the remainder of the extended forecast, there’s a slight chance of precipitation. A warm front will drudge its way across the state producing scattered rain as it moves. Usually when there’s a warm front, a cold front follows, and that’s exactly what we can expect for the beginning of the next work week. Afternoon high temperatures will once again climb back into the upper 60s and low 70s on Monday, but that cold front will pass with a chance of showers and even some thunderstorms. It appears that the remainder of your work week will stay mild with temperatures remaining above average; however, each day brings a chance of scattered rain and possible more thunderstorms.

Forecast Discussion:

As that last line of storms moved out of the viewing area around 2:45am so did our chances for any additional severe weather. Even as the cold front to our west pushes eastward throughout the day heavy rainfall will evade the region with the exception of an isolated thunderstorm mixed in with our scattered showers. The last of our rain will move out as this cold front kicks east, we’ll receive a brief period of dryness along with some much cooler temperatures over the next couple of days. After falling into the upper 30s overnight, Friday’s afternoon highs are expected to climb into the upper 40s as a combination of northerly winds and upper level cloud cover keeps temperatures around 14° below average. While we still expect partly cloudy skies for Saturday, we’ll see enough sunshine to push temperatures back into the 50s that afternoon. High pressure will supply us with southerly winds by Sunday assisting in our 66° afternoon high temperature. However, a warm front could bring some scattered rainfall to the region that afternoon, essentially setting us up for another stormy beginning to the work week. Scattered showers and thunderstorms are expected with a slow passing cold front for both Monday and Tuesday, though temperatures are anticipated to reach the low 70s each of those days.


Update

Severe threat is over.  No reports of any tornado damage though several meso-vortices & LEWPs in the squall line passed through Montgomery, Clinton, Carroll, Howard counties (as warmer air & dew points near 60 surged in) promoting Tornado Warning issuance.

We did have some wind gusts measured at 50-64 mph, however.

Be aware of areas of flash flooding tonight.

Storms Rotating Some As Warmer Air Comes In

April 11th, 2013 at 1:24 am by under Chad's WLFI Weather Blog

Seeing mesoscale couplets in line.  Some brief tornado signatures in the line Clinton, Carroll, Howard, Montgomery counties.  Wind gusted to 52 mph at Crawfordsville & 60 mph at Frankfort. 

Tornado Warnings Clinton, Tippecanoe, Montgomery, Carroll, Howard until 1:45 p.m.


Update

April 11th, 2013 at 12:58 am by under Chad's WLFI Weather Blog

Autumn’s Pine Village weather station gusted to 34 mph at 12:52 a.m. as squall line passed.  This is verified by radar wind data.

Looks like Covington gusted to 38 mph.

The only segment of the line really capable of strong winds is Romney to Linden to Fincastle.  Still think some 55 mph gusts possible there.

Strong Wind Gusts Possible Southern Fountain County

April 11th, 2013 at 12:40 am by under Chad's WLFI Weather Blog

Some strong gusts are likely making it to ground in places in Fountain County with temperatures around 60 & dew point around 60.  Gusts to 55 mph possible around Kingman, Centennial, Mackie.  This is headed for Montgomery County.

Squall Line Nearing State Line

April 11th, 2013 at 12:18 am by under Chad's WLFI Weather Blog

Squall line now approaching state line.  Gusts detected in it south of I-74 up to 69 mph.  North of it, gusts of 53 mph detected.  About 15 miles northeast of Champaign, Rantoul, Illinois AWOS measured a gust to 58 mph. 

It is warming up, especially along & south of I-74, so some of those gusts will likely make it to the ground.  We will see if they can penetrate stable inversion (just below where storms are rooted) & make it to the ground farther north.

Bit of hail & still weak, brief, isolated tornado threat will exist, mainly in southern areas, but we all need to be on-guard.

We have had lots of Severe T’storm Warnings in eastern Illinois, but none issued for viewing area yet.
