WW 566 SEVERE TSTM IA IL MO 300900Z - 301400Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 566 NWS Storm Prediction Center Norman OK 400 AM CDT Tue Jul 30 2024 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Southeast Iowa Northwest Illinois Far Northeast Missouri * Effective this Tuesday morning from 400 AM until 900 AM CDT. * Primary threats include... Scattered damaging winds and isolated significant gusts to 75 mph possible SUMMARY...A cluster of storms will continue southeastward across the region early this morning and potentially pose a risk for damaging winds. The severe thunderstorm watch area is approximately along and 35 statute miles north and south of a line from 10 miles west southwest of Ottumwa IA to 30 miles east of Burlington IA. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU6). 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 1 inch. Extreme turbulence and surface wind gusts to 65 knots. A few cumulonimbi with maximum tops to 500. Mean storm motion vector 30040. ...Guyer Read more

MD 1739 CONCERNING SEVERE THUNDERSTORM WATCH 566... FOR SOUTHEAST IA...FAR NORTHEAST MO...AND FAR WEST-CENTRAL IL
Mesoscale Discussion 1739 NWS Storm Prediction Center Norman OK 0407 AM CDT Tue Jul 30 2024 Areas affected...southeast IA...far northeast MO...and far west-central IL Concerning...Severe Thunderstorm Watch 566... Valid 300907Z - 301030Z The severe weather threat for Severe Thunderstorm Watch 566 continues. SUMMARY...A long-lived cluster moving into southeast Iowa and adjacent portions of Missouri/Illinois may continue to produce strong to localized severe gusts into mid-morning. A downstream severe thunderstorm watch was recently coordinated with WFO DVN. DISCUSSION...An organized cluster/short-line segment has sporadically produced severe wind gusts to around 65 mph in the Des Moines and Chariton areas over the past couple hours. While cloud tops have warmed and the northern portion of the cluster has diminished, its evolution along the MLCAPE gradient has likely aided in maintaining its organized character. Time-series of DMX VWP data indicate a sustained 50-55 kt rear-inflow jet on the backside of the cluster. A general east-southeastward movement is anticipated over the next few hours across southeast IA into far west-central IL and far northeast MO. ..Grams.. 07/30/2024 ...Please see www.spc.noaa.gov for graphic product...

Day 4-8 Outlook
Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0354 AM CDT Tue Jul 30 2024 Valid 021200Z - 071200Z ...DISCUSSION... On Friday and into the weekend, a mid-level trough will slow and eventually stall across the eastern CONUS. Given remnant moisture, expect widespread thunderstorm activity. However, severe weather should be limited by weak shear in the region. A large-amplitude mid-level ridge which is forecast to build across the western CONUS on Thursday and Friday will start to deamplify over the weekend as a series of mid-level shortwave troughs traverse British Columbia and Alberta. The exact evolution of the pattern over the weekend and beyond remains uncertain. There is consensus for multiple mid-level troughs to move through the northern CONUS with at least some lee troughing across the northern Plains. Some severe weather is possible with any of these passing impulses. However, uncertainty remains too high at this time for severe weather probabilities. Read more
