An upper-level disturbance associated with a previous cluster of thunderstorms over the Plains produced scattered strong to severe convection across parts of central Illinois during the late evening of July 7th into the early morning hours of July 8th. A few of the cells produced damaging wind gusts of around 60mph and minor wind damage.

NWS Lincoln, IL wrote its last area forecast discussion before the first event at Jul 7, 11:12 PM CST, 53 minutes earlier.
Area Forecast Discussion National Weather Service Lincoln IL 1212 AM CDT Tue Jul 8 2014 .DISCUSSION... ISSUED 900 PM CDT Mon Jul 7 2014 A line of strong to severe storms has developed in N MO and is projected to move SSE the rest of the evening. The counties included in SVR watch 401 were just our far SW four counties, from Schuyler to Scott/Morgan. Some indications that we will be on the far edge of any severe potential with this line of storms, but enough instability is in place across central IL to support vigorous updrafts and damaging downburst winds. The main hazard from this line of storms looks to be damaging winds with hail more of a secondary threat. Very heavy rainfall rates over short periods of time could lead to localized flooding, so that will remain a concern as well. Timing tools show the storms reaching Schuyler county around 11 pm and Jacksonville around midnight. The remainder of our counties could miss the heavy rains. May reduce PoPs NW of Lincoln based on current trends, but confidence is not high enough to remove PoPs in the NW half of central IL with this update. With the earlier arrival of this complex, tomorrow morning could end up being relatively dry in the southeast, without a need for the likely PoPs we have in there. Mild and muggy conditions are expected for much of the night, with little airmass change except for brief cooling near thunderstorm outflows. Temps and dewpoints look on track. Main update was to add watch info and adjust PoPs and weather to match expected trends tonight. && .AVIATION... ISSUED 1210 AM CDT Mon Jul 7 2014 MCS with strong to severe thundersorms over northern MO and moving east into west central IL, will move across the central IL airports overnight especially impacting I-72 TAF sites. Thunderstorms with IFR to MVFR conditions should reach SPI around 0630Z and DEC by 0730-08Z and CMI between 0830-09Z. Mainly showers to affect northern TAF sites of PIA and BMI overnight with MVFR conditions as thunderstorms appear to stay just south of these airports as they move east. Have convection diminishing late tonight between 10-13Z as MCS moves east and se of central IL by Tue morning. Some light fog/haze possibly lingering into early Tue morning. MVFR to VFR ceilings should scatter out from west to east between 16Z-19Z with VFR conditions then prevailing rest of day Tue and Tue evening. South winds of 4-8 kts early overnight to veer WSW and increase to near 10 kts later tonight as MCS moves in and then veer WNW and increase to 10-15 kts during Tue morning with gusts 18-23 kts Tue afternoon. West winds to diminish to around 5 kts after sunset Tue as weak high pressure settles into the MS river valley. 07 && .PREV DISCUSSION... ISSUED 259 PM CDT Mon Jul 7 2014 Main focus for this forecast will be the thunderstorms expected to impact the area late tonight through tomorrow. More thunderstorms will be possible late in the week and into next weekend as well. Models continue to have a good handle on the overall pattern and surface features, and finally look similar with location and timing of pcpn next 24hrs. There are some differences with the pcpn, but overall they all look similar in timing of the pcpn, start and finish, with NAM being slowest with exiting the pcpn. Still, a blend in the models, combined with persistence looks like a good forecast. SHORT TERM...Tonight through Thursday night Pcpn could be ongoing in the extreme southeast part of the cwa late this afternoon, but should get pushed out of the area quickly. Am expecting the remainder of the evening hours, til midnight to be dry as this boundary gets south of the area and the next weather system does not get into the area til just after midnight. Models all point to an MCS developing somewhere around NW MO/NE KS/ SW MO/SE IA late this evening. Temp and moisture convergence, Omega, and other dynamics support this location and scenario tonight. This MCS is expected to move east to southeast tonight and begin to effect west central IL around midnight and then move ESE through the southern half of the state after midnight tonight. Along with this, there is a sfc front to be the focus of the storms and good low level jet pumping the high moisture content air into the front. So, storms with heavy rainfall, intense lightning, and damaging winds will be possible late tonight and into tomorrow morning. Highest pops for tomorrow will be in the southeast as this will be near the track of this MCS. These storms should move out of the area quickly and leave dry weather for remainder of the short term period, through Thursday night. Temps will finally cool and be at or below normal for the period. Model guidance looked ok. LONG TERM...Friday through Monday Upper level flow will remain out of the northwest with ridging taking place well west. However, in the northwest flow, another frontal system will develop out in the plains and slowly move east toward the area. The first time this system should effect the area with pcpn is Fri night, with slight chance pops. Mentionable pops will begin Friday night and continue through the remainder of the forecast period. Temps will start cool but then warm back up to more hot and humid weather by the weekend. Auten && .ILX WATCHES/WARNINGS/ADVISORIES... NONE. &&
