MD 1768 CONCERNING SEVERE THUNDERSTORM WATCH 539... FOR LOWER MISSOURI VALLEY
Mesoscale Discussion 1768 NWS Storm Prediction Center Norman OK 0928 PM CDT Wed Jul 23 2025 Areas affected...Lower Missouri Valley Concerning...Severe Thunderstorm Watch 539... Valid 240228Z - 240430Z The severe weather threat for Severe Thunderstorm Watch 539 continues. SUMMARY...Gusty winds may accompany storms across eastern Nebraska into extreme western Iowa. New severe thunderstorm watch is not anticipated. DISCUSSION...Frontal convection has grown upscale and matured into an MCS over eastern NE early this evening. Leading edge of this complex is likely producing gusty winds as it propagates slowly across eastern portions of ww539. 00z sounding from OAX exhibits substantial PW (~2 inches), strong buoyancy, but weak deep-layer shear. With an expanding precip shield it appears this activity will easily propagate across the MO River, potentially spreading downstream along the frontal zone as it sags south across IA. While substantial instability resides across this region, greatest severe risk should be gusty winds, and mostly sub-severe, and a new ww is not currently planned. ..Darrow.. 07/24/2025 ...Please see www.spc.noaa.gov for graphic product...

WW 539 SEVERE TSTM KS NE 232140Z - 240500Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 539 NWS Storm Prediction Center Norman OK 440 PM CDT Wed Jul 23 2025 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of North-Central Kansas Central and Eastern Nebraska * Effective this Wednesday afternoon from 440 PM until Midnight CDT. * Primary threats include... Scattered large hail and isolated very large hail events to 2 inches in diameter possible Scattered damaging wind gusts to 70 mph possible SUMMARY...Thunderstorm coverage has gradually increased this afternoon across northeast/north-central KS into central NE. A strongly unstable airmass is in place across the region, supporting the potential for robust updrafts capable of large hail. Strong downdrafts could also contribute to damaging gusts as storms collapse. The severe thunderstorm watch area is approximately along and 80 statute miles east and west of a line from 55 miles northwest of Norfolk NE to 50 miles south of Mccook NE. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU9). 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. && OTHER WATCH INFORMATION...CONTINUE...WW 538... AVIATION...A few severe thunderstorms with hail surface and aloft to 2 inches. Extreme turbulence and surface wind gusts to 60 knots. A few cumulonimbi with maximum tops to 500. Mean storm motion vector 24020. ...Mosier Read more

Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0807 PM CDT Wed Jul 23 2025 Valid 240100Z - 241200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FOR PARTS OF NE INTO THE UPPER MIDWEST...AND ALSO FOR NORTHWEST LOWER MI... ...SUMMARY... Strong to severe storms remain possible this evening from parts of Nebraska into the upper Midwest and northern Lower Michigan, and also across the northern High Plains. ...NE into the Upper Midwest and northern Lower MI... Strong to severe storms are ongoing this evening from central NE into southern MN/northern IA. Very rich low-level moisture and strong buoyancy remain in place along/south of a composite front/outflow, though deep-layer flow/shear is relatively modest along/south of the boundary. Considering the favorable buoyancy, some threat for damaging gusts will persist through the evening, especially if any stronger clusters or bowing segments (like the one currently in central NE) become established within the larger region of ongoing convection. Isolated hail will also be possible with the strongest updrafts. Farther east, a well-defined bowing storm cluster is moving across Lake Michigan toward northern Lower Michigan. Decreasing buoyancy and increasing CINH with eastward extent should eventually result in a weakening trend with this system, but some threat for at least localized wind damage may continue into parts of northwest and possibly north-central lower MI this evening. ...Northern High Plains... Ongoing storms approaching the NE Panhandle should generally weaken with time as they encounter decreasing instability, though localized hail and severe gusts cannot be ruled out this evening. Farther west, isolated strong to severe storms remain possible across northeast WY and vicinity this evening, within a modestly unstable but favorably sheared environment. ..Dean.. 07/24/2025 Read more

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
800 PM EDT Wed Jul 23 2025

For the North Atlantic...Caribbean Sea and the Gulf of America:

North-Central and Northeastern Gulf:
A trough of low pressure over the northeastern Gulf is producing
widely scattered showers and thunderstorms. Over the next day or
two, this system is forecast to move west-southwestward to
westward into the north-central portion of the Gulf where some slow
development is possible. By this weekend, the system is likely to
move inland, ending its chances for development. Regardless of
tropical cyclone formation, locally heavy rainfall is possible for
portions of Florida over the next day or so, and for the northern
Gulf coast through this weekend.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 7 days...low...10 percent.

SPC Day 3-8 Fire Weather Outlook

3 weeks 6 days ago
SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0500 PM CDT Wed Jul 23 2025 Valid 251200Z - 311200Z ...Synopsis... A compact, mid to upper-level closed low will traverse central CA D3/Friday. This feature will open/phase with a Pacific trough D4/Saturday and then lift northeastward over the Great Basin and central Rockies. Through this weekend, a subtropical ridge will begin to dominate the central and southern CONUS. Thereafter, deeper southerly flow aloft is anticipated to develop on its western fringe from southern CA through the Pacific Northwest. ...D3/Friday... Mid-level ascent and moisture accompanying the upper low will lead to the development of showers and thunderstorms along a residual boundary from northern CA, eastward into WY. Inverted "V" forecast soundings, low QPF, and PWATs less than 0.75" over mostly receptive fuels suggest the potential for isolated dry thunderstorms. Farther north localized breezy westerly winds are expected in the gaps of the Cascades of WA and OR near the border, although only a brief drop to near critical RH precludes the need for low probabilities. ...D4/Saturday... An increase in south-southwesterly mid-level flow is expected over the Southwest and central Rockies as the shortwave trough progresses eastward. A well mixed boundary layer from northwest AZ to far western CO should allow for some of this modest flow to translate to the surface, aiding in localized breezy conditions there. A couple of small low probability areas were considered for these areas where fuels are receptive and low RH is anticipated. However, given the isolated nature of critical conditions and lower confidence in occurrence they were not included in the forecast at this time. ..Barnes.. 07/23/2025 ...Please see www.spc.noaa.gov/fire for graphic product...
