SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0130 AM CDT Tue Apr 15 2025 Valid 161200Z - 171200Z ...CRITICAL FIRE WEATHER AREA FOR SOUTHEAST ARIZONA AND SOUTHWEST/WEST-CENTRAL NEW MEXICO... ...Synopsis... An upper low off the southern California coast will begin to phase with a trough within the Northwest. Strong mid-level winds will develop over the Southwest by late afternoon. A surface low will deepen near the Colorado/Kansas border. ...Southwest... A broad area of elevated to critical fire weather is expected from southern/eastern Arizona into much of New Mexico and parts of southeast Colorado. Strong mid-level winds and the deepening surface low will combine to promote 15-25 mph surface winds (highest in terrain-favored areas). Critical fire weather is most likely to occur from southeast Arizona into southwest/west-central New Mexico. Here, strong winds will combine with areas of 5-15% RH. Elsewhere within the region, combinations of weaker winds and slightly higher RH (10-20%) will preclude critical highlights. ..Wendt.. 04/15/2025 ...Please see www.spc.noaa.gov/fire for graphic product...

SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0128 AM CDT Tue Apr 15 2025 Valid 151200Z - 161200Z ...Synopsis... A cold front will move off the East Coast, leaving a dry airmass in its wake. A surface high will push cooler air into the Plains and into parts of the southern Rockies. A belt of stronger mid-level winds will be present within the Southwest. Embedded shortwave troughs may further enhance these winds locally. ...Arizona/New Mexico... The shortwave trough expected to impact eastern Arizona and western New Mexico has had a slight weakening trend in guidance. Even so, some enhancement to the mid-level winds are expected to occur during the afternoon. West of the cold air intrusion in the southern Rockies, temperatures will warm into the 80s to perhaps near 90 F. This will support RH of 15-20%. Winds will not be particularly strong, but 15 mph with localized pockets of 20 mph is possible.

SPC 0600Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1237 AM CDT Tue Apr 15 2025 Valid 161200Z - 171200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS IN A PORTION OF THE CENTRAL GREAT PLAINS... ...SUMMARY... Isolated severe thunderstorms, with a primary threat of large hail, are possible on Wednesday evening/night across parts of the central Great Plains. ...Synopsis... A northern-stream shortwave trough is expected to dig southward from the Canadian Rockies into the northern Intermountain West. A southern-stream, lower-amplitude shortwave trough will drift towards the southern CA coast. A pair of lee cyclones will develop near the Black Hills and the CO/KS border area by Wednesday evening. ...Central Great Plains... Just-in-time modified moisture return from south TX is anticipated by early evening, yielding potential for isolated high-based thunderstorm development near the southwest KS/far northwest OK border area. This portion of the dryline, to the east-southeast of the aforementioned cyclone, will have the best chance of sustaining deep convection with overlap of the low-level thermal ridge/weak buoyancy. Substantial veering of the wind profile with height could support a high-based supercell or two with severe hail/wind. The 00Z HRW-FV3 is a distinct outlier in indicating potential for a discrete supercell deeper into the evening across south-central KS, that impinges on greater low-level moisture amid enlarged low-level hodograph curvature. Bulk of guidance otherwise suggests a substantial increase in MLCIN after sunset as the low-level jet intensifies from west TX into KS, with convection probably struggling given the sub-optimal moisture relative to the stout EML. Elevated convection should form later Wednesday night into early morning Thursday, along the leading edge of the 700-mb warm front and towards the exit region of the low-level jet. Although this convection may remain rooted near 700 mb, favorable speed shear through the cloud-bearing layer should offer a risk of isolated severe hail overnight towards the Lower MO Valley. ..Grams.. 04/15/2025 Read more

MD 0452 CONCERNING SEVERE THUNDERSTORM WATCH 139... FOR NORTHERN AND CENTRAL VIRGINIA
Mesoscale Discussion 0452 NWS Storm Prediction Center Norman OK 0740 PM CDT Mon Apr 14 2025 Areas affected...Northern and central Virginia Concerning...Severe Thunderstorm Watch 139... Valid 150040Z - 150215Z The severe weather threat for Severe Thunderstorm Watch 139 continues. SUMMARY...The primary corridor for large hail and damaging winds will exist along the southern edge of WW 139 in central Virginia. Farther north, isolated strong/damaging winds remain possible. DISCUSSION...The primary corridor of severe risk will likely be within parts of central Virginia this evening. A supercell currently in Nelson County will be capable of large hail and damaging winds. This lead supercell has shown a tendency to move more east-northeast the last half hour, suggesting it may be transitioning to being slightly elevated. Even so, MRMS data suggests large hail is occurring. Other strong to severe storms are training behind the lead supercell and will also pose a threat for large hail and damaging winds. In northern Virginia, temperatures have diabatically cooled as broad area of precipitation has overspread the area. Some elevated instability still remains and the KRLX VAD showed 35-45 kts of flow behind the passing convection. With the Dulles 00Z observed sounding showing 7 C/km lapse rates and a dry sub-cloud layer, a strong/damaging gust could still occur where any convective cores develop. ..Wendt.. 04/15/2025 ...Please see www.spc.noaa.gov for graphic product...

WW 139 SEVERE TSTM VA WV 142250Z - 150500Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 139 NWS Storm Prediction Center Norman OK 650 PM EDT Mon Apr 14 2025 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Northern and Central Virginia Eastern West Virginia * Effective this Monday night and Tuesday morning from 650 PM until 100 AM EDT. * Primary threats include... Scattered damaging wind gusts to 70 mph likely Scattered large hail and isolated very large hail events to 2 inches in diameter possible SUMMARY...Supercells will continue to move eastward this evening while posing a threat for large to very large hail up to 1-2 inches in diameter. Scattered damaging winds with peak gusts of 60-70 mph will also be likely with any clusters that can form while also spreading quickly eastward. The severe thunderstorm watch area is approximately along and 55 statute miles north and south of a line from 35 miles northwest of Staunton VA to 35 miles north of Richmond VA. 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 138... AVIATION...A few severe thunderstorms with hail surface and aloft to 2 inches.
