Tropical Weather Outlook
NWS National Hurricane Center Miami FL
200 AM EDT Thu Jul 17 2025

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

Northeastern and north-central Gulf (AL93):
Recent satellite wind data, in combination with surface and radar
observations, indicate the broad area of low pressure located over
the far northern portion of the Gulf remains quite disorganized. In
addition, the associated shower and thunderstorm activity remains
displaced well west of the broad center. While some additional
development of this system remains possible over the next 12-24
hours, its current structure suggests its chances of developing into
a tropical depression before it reaches the Louisiana coast later
today are decreasing.

Regardless of development, heavy rainfall could produce localized
flash flooding over portions of the north-central Gulf Coast through
Friday. For additional information, please refer to products issued
by the Weather Prediction Center and your local National Weather
Service office.
* Formation chance through 48 hours...low...30 percent.
* Formation chance through 7 days...low...30 percent.

This year was shaping up to be Utah’s most active wildfire season in five years as 574 wildfires blackened more than 83,000 acres through the morning of Thursday, July 17. KSL.com (Salt Lake City, Utah), July 17, 2025 Utah has had more than 380 wildfires that have burned over 43,000 acres so far this year. The fires significantly stressed farms, ranches, rangelands and wildlife habitat across Utah. Gephardt Daily (South Jordan, Utah), June 27, 2025

MD 1697 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR EXTREME SOUTHWEST KANSAS AND THE OKLAHOMA PANHANDLE
Mesoscale Discussion 1697 NWS Storm Prediction Center Norman OK 0853 PM CDT Wed Jul 16 2025 Areas affected...Extreme southwest Kansas and the Oklahoma Panhandle Concerning...Severe potential...Watch unlikely Valid 170153Z - 170330Z Probability of Watch Issuance...5 percent SUMMARY...Storm cluster will continue discrete propagation into the Oklahoma Panhandle before weakening. Isolated severe gusts will be the main threat through 03-04z. DISCUSSION...A cluster of storms has displayed a tendency for discrete propagation/new development to the southwest, on the immediate cool side of a slow moving front. Per the recent measured gusts as high as 78 mph at DDC, the mesoscale environment remains supportive of severe outflow gusts given lingering steep low-level lapse rates and a narrow zone where MLCAPE is still near 3000 J/kg. The storm cluster will likely spread into the central OK Panhandle from now until 03-04z, with weakening expected thereafter as the low levels stabilize gradually. In the interim, occasional severe outflow gusts will remain possible, but the area affected and the duration of the threat are too confined for a watch. ..Thompson/Hart.. 07/17/2025 ...Please see www.spc.noaa.gov for graphic product...

WW 519 SEVERE TSTM CO NE WY 162040Z - 170400Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 519 NWS Storm Prediction Center Norman OK 240 PM MDT Wed Jul 16 2025 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Eastern Colorado Nebraska Panhandle Southeast Wyoming * Effective this Wednesday afternoon and evening from 240 PM until 1000 PM MDT. * 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 A tornado or two possible SUMMARY...Scattered thunderstorms developing near Interstate 25 will continue to intensify this afternoon and move eastward across the Watch. Appreciably strong deep-layer shear will support a mix of supercells and severe multicells across mainly the northern half of the Watch. Large hail and severe gusts will be the primary hazards with the stronger storms, but a tornado is possible. Severe thunderstorms posing primarily a severe-wind risk are possible later this evening as storms congeal into a likely cluster across southeast Colorado. The severe thunderstorm watch area is approximately along and 65 statute miles east and west of a line from 40 miles north of Cheyenne WY to 25 miles west southwest of Springfield CO. 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 517...WW 518... 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.

Overall, the threat is likely to diminish and downstream watch issuance is unlikely. DISCUSSION...A line of storms moving across northern Indiana has shown signs of weakening over the last hour. A couple of reports around 40-55 mph were noted earlier. The downstream air mass remains unstable but deep layer shear is overall marginal. CAM guidance generally suggests this line will continue to weaken with loss of daytime heating. A downstream watch is unlikely to be needed. ..Thornton.. 07/16/2025 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...CLE...ILN...DTX...IWX...GRR...IND...

Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0750 PM CDT Wed Jul 16 2025 Valid 170100Z - 171200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FROM EASTERN CO TO THE LOWER MO VALLEY...LOWER MI TO THE LOWER OH VALLEY...AND THE MID-ATLANTIC... ...SUMMARY... Isolated severe thunderstorms remain possible tonight across eastern Colorado to the Lower Missouri Valley. Isolated damaging winds remain possible this evening across parts of the Midwest and the Mid-Atlantic States. ...Eastern CO to the Lower MO Valley... A trio of rather widely-spaced and recently weakening supercells are ongoing across eastern CO to southwest KS. With pronounced MLCIN downstream, that will further increase nocturnally, these surface-based storms should diminish. Widespread elevated convection is expected across northern KS into the Lower MO Valley overnight, north of the southward-sagging cold front. Marginal severe hail will be possible with initial updrafts before clustering in a largely west/east-orientation. Modest effective bulk shear will limit the overall threat. ...Lower MI/Lower OH Valley to the Mid-Atlantic States... A generally weakening broken line of convection is ongoing from western Lower MI to southern IL. The MI portion has shown some recent uptick, closer to the MCV over central Lake MI. Adequate deep-layer shear and the recent convective increase may foster a sporadic damaging wind threat. But the downstream airmass of weak lapse rates and MLCAPE, as sampled by the 00Z DTX/APX soundings, will marginalize severe potential tonight. Farther east, slow-moving thunderstorms will drift east and/or weaken across parts of the Mid-Atlantic States tonight. But pockets of moderate buoyancy and modest deep-layer shear could support localized damaging winds for a few more hours. ..Grams.. 07/17/2025 Read more

DISCUSSION...Thunderstorm activity continues across Lake Michigan and portions of northern/central Michigan. Overall, this activity is remaining below severe limits. CAM guidance suggest that some re-intensification could occur as they move inland over the next couple of hours. The air mass across Michigan remains favorably unstable, with sufficient deep layer shear for organization around 30-40 kts. It is uncertain if storms will pose a more organized severe threat moving inland. Trends will be monitored across this region but a watch is unlikely to be needed. ..Thornton/Hart.. 07/17/2025 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...DTX...APX...GRR...
