Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0441 PM CDT Wed Jul 09 2025 Valid 111200Z - 171200Z ...Days 3-4/Friday-Saturday... A building mid-level ridge across the Western U.S. will promote lighter winds overall but steadily increasing temperatures across the region through the weekend. Farther east, a mid-level trough moving through the northern High Plains Days 3-4/Friday-Saturday will usher in cooler, post-frontal flow into much Northern/Central Plains through the weekend while also bringing scattered showers/thunderstorms to the central and southern High Plains, with wetting rains remaining along and east of the Continental Divide. ...Days 5-6/Sunday-Monday... Another mid-level trough translating southeastward from British Columbia into the Northern Tier states could bring a thunderstorm threat to portions of the Northern Rockies and MT High Plains Day 5/Monday but a deeper moisture plume could limit dry thunderstorm potential. Higher confidence exists for dry and breezy conditions across the Columbia River Basin on Sunday as stronger mid-level flow promotes dry, downslope winds into the basin, as well as accelerated valley winds across the Snake River Plain amid dry fuels and low RH on Monday. ...Day 7-8/Tuesday-Wednesday... A West Coast thermal trough will promote well above normal temperatures and low relative humidity across the coastal ranges of northern CA, OR and WA but winds appear to remain light from latest model guidance consensus. Additionally, confidence remains low of a return of deeper monsoon moisture into the Southwest around midweek, precluding introduction dry thunderstorm probabilities at this time. ..Williams.. 07/09/2025 ...Please see www.spc.noaa.gov/fire for graphic product...

MD 1619 CONCERNING SEVERE THUNDERSTORM WATCH 497... FOR FAR NORTHERN NORTH CAROLINA INTO VIRGINIA AND SOUTHERN MARYLAND
Mesoscale Discussion 1619 NWS Storm Prediction Center Norman OK 0249 PM CDT Wed Jul 09 2025 Areas affected...Far northern North Carolina into Virginia and southern Maryland Concerning...Severe Thunderstorm Watch 497... Valid 091949Z - 092145Z The severe weather threat for Severe Thunderstorm Watch 497 continues. SUMMARY...Thunderstorm intensification is ongoing across northern North Carolina into Virginia. An increase in damaging/severe wind potential is expected over the next couple of hours. DISCUSSION...A leading convective band emanating off the Blue Ridge Mountains is becoming established from northern VA into far northwest NC. Latest GOES IR imagery shows rapid cloud-top cooling associated with several deeper embedded convective cores, signifying robust intensification. Buoyancy immediately downstream continues to increase with temperatures warming into the upper 80s/low 90s and MLCAPE approaching 2500 J/kg as of the 20z RAP mesoanalysis. This air mass should promote further intensification over the next several hours and is favorable for strong water-loaded downbursts. At this point, storm mode should primarily be linear given mean flow oriented along the developing band. 25-30 knot bulk shear should support a few embedded surging segments within the line that may pose a few focused corridors of damaging/severe winds with gusts as high as 55-65 mph. Latest guidance hints that this potential should be maximized over the next few hours from the NC/VA border into central VA. ..Moore.. 07/09/2025 ...Please see www.spc.noaa.gov for graphic product...
