SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0444 PM CDT Mon Aug 07 2023 Valid 091200Z - 151200Z ...Portions of Southwestern, Central, and Northwest Texas... Surface low development across the Southern Plains will bring an increase in low-level south to southwesterly flow across southern and central Texas late Tuesday, remaining locally breezy overnight into early Wednesday. Shallow moisture will increase east to west early Wednesday morning but will likely mix out as daytime heating and a deepening boundary allows drier air aloft to mix into the low levels. Afternoon relative humidity reductions to 15-25 percent will be possible amid sustained winds 10-15 mph (gusting 20-30) and daytime temperatures exceeding 100 F degrees. Extremely critical fuels across portions of southwestern, central, and northwestern Texas support introduction of 70 percent Critical probabilities, though winds may be borderline across some portion of the area. Outside of the 70 percent area, a broad 40 percent risk was included for much of central, northwestern, and southwestern Texas. Confidence is lower within these regions as winds will likely remain lighter but Elevated to locally Critical conditions still appear possible. ...Western Colorado, Southern Utah, and Northern New Mexico... Monsoonal moisture will increase across the Southwest late week into the weekend. On the northern fringe of this moisture, some risk of isolated dry thunderstorm development will be possible, mainly across southern Utah, western Colorado, and northwestern New Mexico on D3 - Wed and D4 - Thur. Locally breezy winds will also continue across southern Utah, western Colorado, and central/northern New Mexico D3 - Wed. Breezy and dry conditions will continue in central New Mexico on D4 - Thur. Overall, low confidence in the spatial extent of these threats precludes the need to include any areas at this time. ..Thornton.. 08/07/2023 ...Please see www.spc.noaa.gov/fire for graphic product...

MD 1894 CONCERNING SEVERE THUNDERSTORM WATCH 607... FOR CENTRAL NORTH CAROLINA
Mesoscale Discussion 1894 NWS Storm Prediction Center Norman OK 0447 PM CDT Mon Aug 07 2023 Areas affected...Central North Carolina Concerning...Severe Thunderstorm Watch 607... Valid 072147Z - 072345Z The severe weather threat for Severe Thunderstorm Watch 607 continues. SUMMARY...An organized bowing line segment moving across North Carolina will likely continue eastward for the next couple of hours, regionally increasing the severe/damaging wind threat. DISCUSSION...Latest regional radar imagery and lightning trends show a steady intensification of a bowing line segment across western NC over the past hour. Velocity data from KRAX as well as VWP observations from KMRX hint at the development of a rear inflow jet, which corroborates the noted radar/lightning trends. Although recent RAP mesoanalyses hint at a slight buoyancy deficit immediately ahead of this segment across central NC, modest warm/moist advection from the surface to 925/850 mb will likely help improve the downstream thermodynamic environment ahead of the line. Additionally, 30-40 knot effective-shear vectors oriented nearly orthogonal to the line will compensate for any thermodynamic deficiencies and continue to support line organization. Consequently, there may be a corridor of regionally higher severe/damaging wind potential across central NC over the next 1-2 hours. ..Moore.. 08/07/2023 ...Please see www.spc.noaa.gov for graphic product...

MD 1893 CONCERNING TORNADO WATCH 605... FOR PORTIONS OF EASTERN MARYLAND AND PENNSYLVANIA INTO DELAWARE...WESTERN NEW JERSEY...AND EASTERN NEW YORK
Mesoscale Discussion 1893 NWS Storm Prediction Center Norman OK 0401 PM CDT Mon Aug 07 2023 Areas affected...portions of eastern Maryland and Pennsylvania into Delaware...western New Jersey...and eastern New York Concerning...Tornado Watch 605... Valid 072101Z - 072230Z The severe weather threat for Tornado Watch 605 continues. SUMMARY...The severe threat continues across Tornado Watch 605. All severe hazards remain possible. The severe threat may also develop farther north into eastern NY, where a new WW issuance may be needed. DISCUSSION...Supercell structures across northeast PA, and a QLCS along the PA/MD/VA border area, continue to approach the Hudson Valley (Tornado Watch 605 area). A few instances of low-level rotation have occurred with the northeast PA storms, with continuous reports of damaging gusts being received with the aforementioned QLCS. Over the Hudson Valley, an adequate buoyancy/vertical shear parameter space exists to promote a continued severe threat with the ongoing storms as they approach the Delaware River. Damaging gusts appear to be the main threat given increasing linear storm modes. However, a couple of tornadoes may still occur with persistent supercells and/or QLCS circulations. Adequate buoyancy has also materialized farther north into east-central NY, where approaching storms are also increasing in number and intensity. Pending convective trends, a WW issuance may be needed across portions of the Upper Hudson Valley. ..Squitieri.. 08/07/2023 ...Please see www.spc.noaa.gov for graphic product...

Issued at 200 PM PDT Mon Aug 07 2023 000 WTPZ41 KNHC 072036 TCDEP1 Post-Tropical Cyclone Eugene Discussion Number 10 NWS National Hurricane Center Miami FL EP062023 200 PM PDT Mon Aug 07 2023 Eugene has not had any organized deep convection for over 12 hours now, and since it is over very cold water, no further thunderstorm activity is anticipated. Thus, Eugene has transitioned into a post-tropical cyclone, and this is the last NHC advisory. The initial wind speed is reduced to 30 kt, in accordance with the remaining Dvorak estimates. The system should gradually spin down and become a trough of low pressure in about 2 days. The remnants of Eugene should turn northward tomorrow into a break in the low- level ridge and slow down as it gets caught in weak steering flow. No significant changes were made to the NHC track or intensity forecasts.

Valid 072032Z - 072230Z The severe weather threat for Severe Thunderstorm Watch 601, 604 continues. SUMMARY...The threat for strong to severe winds will continue through the remainder of the afternoon. Storms from far northeast Georgia into western South and North Carolina appear to have the greatest potential. DISCUSSION...Moderate to strong buoyancy exists south of a line of strong to severe thunderstorms from central Alabama into western South and North Carolina. Portions of this activity that are oriented more north-south will likely have greater potential for strong/severe wind gusts, which is the case for western South Carolina into adjacent western North Carolina. The more west-east oriented portions of the line in Alabama/Georgia may still produce wind damage as new updrafts develop along the outflow within the hot/unstable boundary layer. The southern extent of the severe threat is not certain as shear drops off with southward extent. ..Wendt.. 08/07/2023 ...Please see www.spc.noaa.gov for graphic product...
