WW 408 SEVERE TSTM IL IN MI OH LM 131850Z - 140100Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 408 NWS Storm Prediction Center Norman OK 150 PM CDT Thu Jun 13 2024 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Northern Illinois Northern Indiana Southern and Central Lower Michigan Far Northwest Ohio Lake Michigan * Effective this Thursday afternoon and evening from 150 PM until 800 PM CDT. * Primary threats include... Scattered large hail and isolated very large hail events to 2.5 inches in diameter possible Scattered damaging wind gusts to 70 mph possible A tornado or two possible SUMMARY...Thunderstorms are expected to continue increasing in coverage this afternoon while posing a threat for large hail around 1.5-2.5 inches in diameter. Severe/damaging winds of 60-70 mph may also occur as convection moves east-southeastward and potentially grows into one or more small clusters through the afternoon and early evening. The severe thunderstorm watch area is approximately along and 60 statute miles north and south of a line from 20 miles west southwest of Marseilles IL to 10 miles north of Jackson MI. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU8). PRECAUTIONARY/PREPAREDNESS ACTIONS... REMEMBER...A Severe Thunderstorm Watch means conditions are favorable for severe thunderstorms in and close to the watch area. Persons in these areas should be on the lookout for threatening weather conditions and listen for later statements and possible warnings. Severe thunderstorms can and occasionally do produce tornadoes. && AVIATION...A few severe thunderstorms with hail surface and aloft to 2.5 inches. Extreme turbulence and surface wind gusts to 60 knots. A few cumulonimbi with maximum tops to 500. Mean storm motion vector 29030. ...Gleason Read more

SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0452 PM CDT Thu Jun 13 2024 Valid 151200Z - 211200Z Broad cyclonic mid-level flow will persist over the northwestern quadrant of the CONUS through late next week as an upper ridge dominates the central and eastern CONUS. Several days of wildfire-spread potential are evident over the Interior West as multiple mid-level troughs pivot around the broad cyclonic flow aloft. The first in a series of mid-level troughs will overspread the Pacific Northwest on Day 3 (Saturday), with dry and windy conditions overspreading drying fuels to the lee of the Cascades, and farther south across southern portions of the Great Basin. By Days 4-5 (Sunday and Monday), a broader and more amplified mid-level trough will traverse the Interior West, supporting dry and windy conditions atop receptive fuels from portions of the California Valley area, to the Great Basin and Desert Southwest. The best chance for Critically dry and windy conditions atop receptive fuels will be over southern Utah into much of northern and central Arizona and far western New Mexico, where 70 percent Critical probabilities have been added. Thereafter, the mid-level trough will depart the region. Dry conditions will persist, but questions remain regarding the strength of the surface wind field, precluding the addition of Critical probabilities for Days 6-8 (Tuesday-Thursday). ..Squitieri.. 06/13/2024 ...Please see www.spc.noaa.gov/fire for graphic product...

SPC MD 1250

1 year 2 months ago
MD 1250 CONCERNING SEVERE POTENTIAL...WATCH POSSIBLE FOR CENTRAL KANSAS
Mesoscale Discussion 1250 NWS Storm Prediction Center Norman OK 0404 PM CDT Thu Jun 13 2024 Areas affected...Central Kansas Concerning...Severe potential...Watch possible Valid 132104Z - 132200Z Probability of Watch Issuance...60 percent SUMMARY...Scattered thunderstorm development is expected across central KS over the next 1-2 hours. Damaging wind gusts near 65-80 mph and large hail exceeding 1.5" in diameter may accompany a few of the thunderstorms. DISCUSSION...The most recent surface objective mesoanalyis and visible satellite imagery indicate CINH is eroding across central KS this afternoon along a prefrontal surface trough extending east to west. Boundary layer moisture pooling along this feature, along with diurnal heating leading to temperatures in the triple digits, is yielding ~3500 J/kg of MLCAPE amidst very steep mid-level lapse rates. Convective initiation is expected to occur very soon with the deepening cumulus across central KS, but may be delayed further east-northeast where a broader region of MLCINH exists. The initial thunderstorms that develop and remain more discrete will have an opportunity to produce large hail, but considering only modest deep layer effective shear is present, the main severe threat should be damaging wind gusts through early this evening. Increasing thunderstorm coverage over the next couple of hours may require the need for a WW. ..Barnes/Gleason.. 06/13/2024 ...Please see www.spc.noaa.gov for graphic product...
