SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0259 PM CDT Tue Aug 08 2023 Valid 091200Z - 101200Z ...CRITICAL FIRE WEATHER AREA FOR CENTRAL TO NORTH TEXAS... The current D2 Fire Weather Outlook remains on track with no updates needed. See previous discussion for more information. ..Thornton.. 08/08/2023 .PREV DISCUSSION... /ISSUED 0142 AM CDT Tue Aug 08 2023/ ...Synopsis... Fire weather concerns will persist across central to north Texas on Wednesday as a surface trough moves through the region and strengthens low-level winds. More localized concerns may emerge across parts of the Southwest and Great Basin. ...Texas... The upper trough currently approaching the central Rockies is forecast to slowly meander east into the mid-MS Valley by late Wednesday. As this occurs, an attendant surface trough trailing into central TX will migrate east. This will strengthen region pressure gradient winds, with ensemble guidance showing reasonably high probability for sustained 15-20 mph south/southwesterly winds. With exceptionally dry fuels already in place and temperatures exceeding 100 F expected by mid-afternoon, elevated to critical fire weather conditions are expected. There is some uncertainty regarding 1) the potential for wetting rainfall over the next 24 hours (and its impact on fuel status), and 2) the potential for isolated to scattered thunderstorms Wednesday afternoon along the surface trough. These storms may produce beneficial rain and modulate the overall fire threat, or could produce gusty outflow winds and locally exacerbate fire concerns. ...Southwest and Great Basin... More localized elevated fire weather conditions are expected across central NM and western to central NV. Across NM, 15-20 mph gradient winds in the wake of the surface trough are likely and should overlap with RH values in the teens to low 20s. However, recent rainfall has likely mitigated fuel status across this region. To the west, downslope flow in the lee of the Sierra Nevada may support localized elevated conditions across western/southern NV. Ensemble guidance suggests these conditions will remain fairly localized and confined to the immediate lee of the terrain. ...Please see www.spc.noaa.gov/fire for graphic product... Read more

SPC 1730Z Day 2 Outlook
Day 2 Convective Outlook RESENT 1 NWS Storm Prediction Center Norman OK 0111 PM CDT Tue Aug 08 2023 Valid 091200Z - 101200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS FROM SOUTHEASTERN MISSOURI AND NORTHEASTERN ARKANSAS INTO THE TENNESSEE VALLEY... ...SUMMARY... Severe thunderstorms are expected on Wednesday from eastern Oklahoma/Kansas eastward to the Lower Ohio and Tennessee Valley vicinity. ...Synopsis... A mid-level short wave trough, embedded in a belt of enhanced west-southwesterly flow across the central and eastern U.S., will advance steadily east-southeastward, crossing the Mid Mississippi Valley overnight. A belt of enhanced flow in the lower and middle troposphere (40 to 60 kt at mid levels) will spread across the Ozarks through the day, and across the Mid Mississippi Valley into the Ohio and Tennessee Valleys during the evening and overnight. At the surface, a cold front -- trailing from a weak low initially progged over eastern Kansas -- is forecast to shift eastward into the Ozarks and southeastern Oklahoma through the day, and then across the Mid Mississippi and Lower Ohio Valley overnight. By the end of the period, the front should extend from a low over the Ohio vicinity west-southwestward to North Texas. ...Eastern portions of KS/OK eastward into the Ohio Valley/Mid-South/Southeast... Expectations remain that fairly widespread convection will be ongoing at the start of the period across eastern Kansas and Missouri, which should shift eastward through the day into/across the Mid Mississippi/Lower Ohio/Tennessee Valleys. Very limited/local severe risk may be ongoing early, and should increase through the day as the airmass ahead of the convection destabilizes. Locally damaging winds should be the primary severe risk assuming storms intensify as expected, along with potential for hail and a tornado or two. Meanwhile, a second round of convection is forecast to develop in the recovering airmass across the Ozarks vicinity ahead of the advancing cold front during the afternoon/evening, with timing and initial intensity of the convection modulated by prior storms and any lingering cloud cover. Eventually, storms should intensify and grow upscale into one or more clusters -- aided by a 35-45 kt southwesterly low-level jet. At this time, it appears that overall risk for damaging winds -- potential from two separate rounds of storms -- warrants upgrade to ENH risk/30% wind probability across parts of the Mid Mississippi and Tennessee Valleys, which would continue well into the evening hours. ..Goss.. 08/08/2023 Read more

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...
