... Fifth tornado confirmed from Monday - Orland Park...
A storm damage survey of Orland Park conducted by the National
Weather Service has resulted in a fifth tornado confirmed across
northern Illinois and Northwest Indiana from this past monday's
storms.
A very brief EF0 tornado touched down near 135th street and La
Grange Road about 8 PM Monday and tracked to the southeast for a
quarter mile. At that point the tornado was wiped out by a
microburst which continued to the east and southeast producing
additional damage.
Other tornadoes confirmed from Monday are:
At Griffith, in. Rated EF2.
At Bloomingdale, IL. Rated EF1.
At Bolingbrook, IL. Rated EF1.
At Boswell, in. Rated EF0.
Additional details concerning start and end points of the
tornadoes... path length... path width... and damage can be found on

NWS Forecaster Discussion
294 fxus63 klot 072345 afdlot Area forecast discussion National Weather Service Chicago/Romeoville Illinois 645 PM CDT Thursday Aug 7 2008 Discussion... 320 PM CDT A relatively quiet weather pattern is expected to continue through the weekend with main focus on potential for showers Saturday afternoon/evening. Surface ridge axis across the Dakotas will continue to slowly build into the western Great Lakes through tomorrow. A weak upper vorticity maximum progressing through Southern Lower Michigan has aided in scattered shower/thunderstorm development across Michigan this afternoon but not expecting any of these showers to impact northern Illinois or Northwest Indiana this evening. Otherwise with no significant upstream short waves of note...diurnal cumulus will diminish this evening with sunset. Did lower min temperatures a shade for tonight and tomorrow given trends in surface dew points today with fairly good radiational cooling conditions...with highs in the middle to upper 50s except warmer downtown. Quiet weather will continue tomorrow with forecast area in non divergent upper pattern tomorrow across the forecast area between longwave trough across northeast US and southeast Canada and longwave ridge across western Continental U.S./Southwest Canada. Perhaps some more afternoon cumulus tomorrow but expecting coverage to be less than that of today given ridge axis building in and less impressive low/middle level lapse rates. Next feature of interest for weather across northern Illinois and Northwest Indiana will be vorticity lobe currently approaching James Bay. This vorticity lobe is expected to drop southward into lower Michigan on Saturday with tail end of this short wave likely to clip southern Wisconsin/northern Illinois Saturday afternoon. Low/middle level lapse rates will steepen in association with this feature as middle level cool pocket drops into the Great Lakes. Sref probability of precipitation actually increase into the high chance category by late Saturday...but frontal convergence will be quite weak and if anything does develop in association with the weak surface front associated with this wave...expecting only isolated coverage during the afternoon/early evening. Next surface high will quickly build into the area behind this weak front on Saturday night ending any low precipitation chances. Temperatures over the next few days will show little day to day variation given weak thermal advection pattern...and despite continued weaker north winds tomorrow as surface high builds in...relatively Warm Lake temperatures should limit lake cooling to middle/upper 70s. With surface high departing early Saturday...southwest winds on Saturday should limit potential for any lake breeze. Temperatures perhaps a few degrees cooler on Sunday behind this frontal boundary with surface winds back to the northeast providing a few degrees of lake cooling once again. Moisture will slowly creep back into the area later Monday and Tuesday as more amplified upper level short wave moves across the Pacific northwest and sends a series of weaker short waves east dampening upper level ridging a bit. Medium range models are showing some significant differences in upper level evolution beginning of next week with latest GFS more aggressive in phasing another upper low across Hudson Bay with upper level short wave tracking eastward from the northwest US. European model (ecmwf) keeps Hudson Bay upper low on more eastward track into Quebec. Given large uncertainties at this time...did not make many changes to going weather grids with low chance probability of precipitation for thunder during the first part of next week with at least better chance of deamplifying upper ridge and more significant moisture return. Marsili && Aviation... 645 PM CDT 00z tafs...lake breeze boundary has pushed well inland of gyy/Ord/mdw turning winds northeasterly. With winds over northern Illinois a little stronger than over ecntrl Illinois...the lake breeze is not pushing quite as far inland and feel it is unlikely to push through dpa before washing out. Expect that the boundary will dissipate by around 02z and winds will return to more reflective of the large scale flow and return northwesterly overnight. With a weak gradient in place as the center of the large sprawling high builds southeastward...winds will drop off the light/variable overnight...and then return to more northeasterly tomorrow. With a dry airmass in place and large scale subsidence spreading over the region...expect that visby will remain unrestricted through the period and only scattered fair weather cumulus to develop tomorrow during the late morning and afternoon hours. Krein && Marine... 110 PM CDT A large high pressure over southern Saskatchewan will move southeastward...settling over the western Great Lakes and Midwest by Friday evening. The high will then slowly drift southeastward across the Ohio Valley over the weekend...with a ridge remaining over the western Great Lakes. This pattern will allow north northwest winds as high as 25 knots this afternoon...to diminish tonight and become light and variable around 10 knots Friday night. Merzlock && Lot watches/warnings/advisories... Illinois...none. In...none. Lm...Small Craft Advisory...Indiana nearshore waters until 4 PM Friday. && $$
