WW 118 TORNADO IA NE SD 161725Z - 170000Z
URGENT - IMMEDIATE BROADCAST REQUESTED Tornado Watch Number 118 NWS Storm Prediction Center Norman OK 1225 PM CDT Tue Apr 16 2024 The NWS Storm Prediction Center has issued a * Tornado Watch for portions of Western and Northern Iowa Northeast Nebraska Southeast South Dakota * Effective this Tuesday afternoon and evening from 1225 PM until 700 PM CDT. * Primary threats include... A couple tornadoes possible Scattered large hail events to 1.5 inches in diameter possible Isolated damaging wind gusts to 60 mph possible SUMMARY...A tornado/hail risk will exist through the afternoon as far west as northeast Nebraska and southeast South Dakota near a surface low, with other severe storms expected to develop into additional parts of Iowa. The tornado watch area is approximately along and 65 statute miles north and south of a line from 30 miles north of Norfolk NE to 35 miles east of Fort Dodge IA. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU8). PRECAUTIONARY/PREPAREDNESS ACTIONS... REMEMBER...A Tornado Watch means conditions are favorable for tornadoes and 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. && OTHER WATCH INFORMATION...CONTINUE...WW 116...WW 117... AVIATION...Tornadoes and a few severe thunderstorms with hail surface and aloft to 1.5 inches. Extreme turbulence and surface wind gusts to 50 knots. A few cumulonimbi with maximum tops to 450.

MD 0464 CONCERNING SEVERE POTENTIAL...WATCH POSSIBLE FOR PORTIONS OF NORTHERN/CENTRAL IL
Mesoscale Discussion 0464 NWS Storm Prediction Center Norman OK 0340 PM CDT Tue Apr 16 2024 Areas affected...portions of northern/central IL Concerning...Severe potential...Watch possible Valid 162040Z - 162215Z Probability of Watch Issuance...40 percent SUMMARY...Severe potential may slowly increase over the next few hours into parts of northern and central Illinois. A watch may be needed at some point late this afternoon, but timing remains uncertain. DISCUSSION...A band of storms continues to lift northeast across eastern IA into western IL this afternoon. Much of the convection is somewhat disorganized in a messy storm mode. Downstream into northern/central IL, some modest increase in boundary-layer moisture still may occur as a warm front lifts north. While strong heating has occurred, some weak inhibition remains over parts of the area. Nevertheless, modest boundary-layer moisture beneath midlevel lapse rates around 7 C/km are supporting weak instability (MLCAPE 1000 J/kg or less). The initial band of convection moving toward the MCD area may largely remain unproductive. However, as large-scale ascent increasing toward evening, a secondary band of convection may move into the area and post more of a severe risk. Given the somewhat limited thermodynamic environment (despite favorable vertical shear), severe potential may only gradually increase toward evening. The area will be monitored for potential watch issuance, but timing is uncertain. ..Leitman/Guyer.. 04/16/2024 ...Please see www.spc.noaa.gov for graphic product...

MD 0462 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR CENTRAL AND EASTERN ARKANSAS
Mesoscale Discussion 0462 NWS Storm Prediction Center Norman OK 0316 PM CDT Tue Apr 16 2024 Areas affected...central and eastern Arkansas Concerning...Severe potential...Watch unlikely Valid 162016Z - 162145Z Probability of Watch Issuance...20 percent SUMMARY...Isolated large hail is possible this afternoon/evening. DISCUSSION...A plume of rich low-level moisture has advected across eastern Texas, Louisiana and into southern Arkansas. Weak isentropic ascent has been sufficient for storm development on the leading edge of this moist plume. Effective shear of 50 to 55 knots and will be proficient for organized storms, including supercells. However, warm mid-level temperatures and weak ascent will be the primary limiting factor to a greater threat. Therefore, a few stronger storms may develop with a threat for large hail, but this threat is expected to remain too isolated to warrant a watch. ..Bentley/Guyer.. 04/16/2024 ...Please see www.spc.noaa.gov for graphic product...

MD 0463 CONCERNING TORNADO WATCH 118... FOR NORTHERN IOWA
Mesoscale Discussion 0463 NWS Storm Prediction Center Norman OK 0336 PM CDT Tue Apr 16 2024 Areas affected...Northern Iowa Concerning...Tornado Watch 118... Valid 162036Z - 162130Z The severe weather threat for Tornado Watch 118 continues. SUMMARY...The tornado threat within watch 118 is now confined to northern Iowa. DISCUSSION...As the Pacific front interacted with convection across eastern Nebraska around 19Z, a strong outflow boundary pushed well ahead of convection which has essentially ended the severe weather threat for the western half of watch 118. In addition, this outflow boundary has recently collided with the warm front near the intersection of MN/IA/SD and thus, expect the storm which moved north of the boundary to continue to weaken. Therefore, the only remaining favorable airmass is northeast of the dryline across north-central Iowa. In this region, a few tornadoes have been confirmed with the low-topped supercell in Pocahontas county at 2030Z. Visible satellite and radar trends show additional storms developing southeast of this storm which may also pose a tornado threat this afternoon and into the early evening as they move north. ..Bentley.. 04/16/2024 ...Please see www.spc.noaa.gov for graphic product...

SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0337 PM CDT Tue Apr 16 2024 Valid 181200Z - 241200Z An upper-level trough will continue into the Great Lakes and Northeast into the weekend. Models are suggesting that a more amplified western ridge/eastern trough pattern will develop by early next week. A push of cooler air will move into the southern Plains late this week with another push expected during the weekend. Given recent and expected precipitation, fire weather concerns within much of CONUS should remain low. Dry and modestly breezy conditions are expected to remain across parts of the Southwest through part of the weekend, west of a back-door cold font. However, fuels across the region are generally marginally receptive with perhaps the exception of increasingly dry areas of central/western New Mexico. Even so, potential for critical fire weather appears too low for highlights. ..Wendt.. 04/16/2024 ...Please see www.spc.noaa.gov/fire for graphic product... Read more
