UPDATED: Coverage of Monday night's storms

Posted: Updated:

UPDATE 10:30pm

Areas of heavy rain and thunder are falling along and east of the Rock River. Wind gusts of 40 to 50mph are possible behind this area of rain.  Luckily, the severe weather has remained to our east and will affect the Chicago area south to Champaign. More thunderstorms have flared up in eastern Iowa that we will continue to monitor, although severe weather is not currently occurring with this line of storms. -JA

--------------------

UPDATE 9:00pm:

We are streaming live coverage of the thunderstorms moving into the area online. Just head to WREX.COM/LIVE

Chief Meteorologist Eric Sorensen and Meteorologist Joe Astolfi are in the weather center, 13 News Reporters Matt Groves is keeping an eye on the sky in Rochelle, and Storm Chaser Chris Vagasky is on the road in Lee & Ogle County. -JA

--------------------

UPDATE 8:30pm:

A Severe Thunderstorm Watch is in effect until 3am for the entire WREX viewing area.  Stronger thunderstorms are moving into central Illinois and even as far north as Lee County. Strong wind gusts, hail, frequent lightning, and heavy rain are a concern. There is also a very slight chance for an isolated tornado. -JA

--------------------

UPDATE 7:30pm:
All eyes on an arcing batch of thunderstorms developing around Galesburg right now. These are expected to congeal into one, large storm as they move northeast. If this occurs, they will be in Whiteside County by 8:30 and the Rockford Metro before 10pm. Damaging wind would be the main threat, second to large hail, and a remote chance of a tornado.

In addition, within the past minute, a Tornado Warning was issued for the cells just north of Des Moines. However, these storms will move into Western Wisconsin, well northwest of our coverage area.

Please remain alert for rapidly changing weather later this evening and think about your safest place for shelter (likely in the most interior room, away from windows, preferably in the basement under the stairs). -ES

---------------------

UPDATE 5:00pm:
We continue to follow development of thunderstorms, slow to occur this afternoon.

I expect storms will begin popping in Northern Missouri in the next few hours. With a forward movement to the northeast at 45mph, it will take several hours to arrive in our area. Once they get here, we will have a threat of damaging wind and large hail.

An isolated tornado can't be ruled out, but that threat will greatly diminish after 9pm. It remains to be seen whether we will even get storms here by then. Additional storms will fire and head through Northern Illinois and Southern Wisconsin overnight. -ES

---------------------

UPDATE 4:00pm:
A weather watch is expected in the next hour for Central Illinois. We are still waiting for activity to pop in Northern Missouri. These storms will affect the area this evening.

There is very little activity right now, but that is expected to increase later this evening. It remains to be seen whether we will have widespread severe weather, but the conditions are favorable later this evening, especially with increasing jet-stream level wind. Damaging wind and large hail will be the primary threat, along with a slight chance of a tornado this evening.

An additional severe thunderstorm threat continues tonight and Tuesday. -ES

---------------------

UPDATE 3:00pm:
Temperatures are currently rising into the middle 80s at 3pm with dewpoints in the 60s. Exactrack|HD remains void of storms right now. However, that will change in the next several hours.

Thunderstorms will most likely initiate in Northern Missouri late this afternoon, tracking northeast. They will reach the Rockford Metro around sunset tonight. The greatest potential for severe weather will be in the form of damaging wind and large hail. If moisture increases sufficiently enough, a few tornadoes will be possible between 7-10pm.

No watches are currently in effect, however with the onset of storms in Northern Missouri by 5pm, I would expect some sort of weather watch to be issued for most, if not all, of Northern Illinois by 5pm. Depending on how these storms materialize, they could continue through the wee hours of Tuesday. -ES

--------------------------------

The 13 Weather Authority is in Severe Weather Mode in preparation of heavy storms expected this afternoon into this evening.

Ample sunshine for the better part of the morning has lead to rapid heating heading into the afternoon hours. This heat in combination with a very unstable humid atmosphere puts us at a Threatrack Level 3.

The threat for possible severe storms looks to be mainly focused on the late afternoon and evening hours. Damaging wind and hail are likely with the possibility of tornadoes as well. -GB
