SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0428 PM CDT Sat Jun 29 2024 Valid 011200Z - 071200Z While initially limited in scope, fire-weather concerns appear likely to increase through the extended forecast period as a strong ridge of high pressure builds over the West Coast. Very hot temperatures and dry surface conditions should gradually increase fire danger over much of the West, as stronger northwest flow over the Great Basin will continue through mid to late week. Ridge breakdown is expected late in the forecast period as early as next weekend. Uncertainty on the character of the pattern following this transition remains high, but dry and breezy conditions are possible through much of next week and into next weekend across the interior Northwest and Great Basin ...Interior Pac. Northwest & northern Great Basin... As the ridge builds quickly this weekend, enhanced flow aloft will develop along the eastern periphery as a weak trough moves south out of Canada. At the surface, a weak cold front should move south into the Great Basin, enhancing surface winds and the chance for isolated thunderstorms over parts of OR, NV, UT, and ID. Isolated critical fire-weather conditions could occur D3/Mon as the gusty winds and low RH spread through the northern Great Basin and Snake River Valley. Behind the front, dry northwesterly surface flow should continue through the first part of the week as the ridge aloft intensifies. Very warm temperatures should allow for an increase in fire danger indices through the week before another shortwave trough and cold front pass along the eastern portion of the ridge D5/Wed and D6/Thur. Gusty surface winds are likely over portions of the northern Great Basin and southern ID along, with very dry surface conditions. With increasingly dry fuels, critical fire-weather conditions may develop. At the end of the forecast period, most medium-range guidance shows the upper-ridge breaking down ahead of a trough moving into the Pacific Northwest. It remains unclear exactly how this transition will evolve, with some guidance showing an increase in showers and thunderstorms, while others show a more substantial increase in hot, dry and windy conditions with trough passage. Regardless of the outcome, an increase in fire-weather potential is very likely, owing to the antecedent hot and dry conditions beneath the weakening ridge. ...Northern CA... Under the ridge aloft, a thermal trough is likely to extend from the Desert Southwest through northern CA, leading to poor RH recovery and occasional gusty winds from early to mid week next week. Gusty northerly winds are possible in portions of northern CA, especially in/around the Sacramento Valley. Drying fuels and the increase in temperatures are likely to support at least some isolated fire-weather risk through the next several days, though the exact coverage and duration are currently unclear. ..Lyons.. 06/29/2024 ...Please see www.spc.noaa.gov/fire for graphic product...

Very warm temperatures should allow for an increase in fire danger indices through the week before another shortwave trough and cold front pass along the eastern portion of the ridge D5/Wed and D6/Thur. Gusty surface winds are likely over portions of the northern Great Basin and southern ID along, with very dry surface conditions. With increasingly dry fuels, critical fire-weather conditions may develop. At the end of the forecast period, most medium-range guidance shows the upper-ridge breaking down ahead of a trough moving into the Pacific Northwest. It remains unclear exactly how this transition will evolve, with some guidance showing an increase in showers and thunderstorms, while others show a more substantial increase in hot, dry and windy conditions with trough passage. Regardless of the outcome, an increase in fire-weather potential is very likely, owing to the antecedent hot and dry conditions beneath the weakening ridge. ...Northern CA... Under the ridge aloft, a thermal trough is likely to extend from the Desert Southwest through northern CA, leading to poor RH recovery and occasional gusty winds from early to mid week next week. Gusty northerly winds are possible in portions of northern CA, especially in/around the Sacramento Valley. Drying fuels and the increase in temperatures are likely to support at least some isolated fire-weather risk through the next several days, though the exact coverage and duration are currently unclear. ..Lyons.. 06/29/2024 ...Please see www.spc.noaa.gov/fire for graphic product...

SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0428 PM CDT Sat Jun 29 2024 Valid 011200Z - 071200Z While initially limited in scope, fire-weather concerns appear likely to increase through the extended forecast period as a strong ridge of high pressure builds over the West Coast. Very hot temperatures and dry surface conditions should gradually increase fire danger over much of the West, as stronger northwest flow over the Great Basin will continue through mid to late week. Ridge breakdown is expected late in the forecast period as early as next weekend. Uncertainty on the character of the pattern following this transition remains high, but dry and breezy conditions are possible through much of next week and into next weekend across the interior Northwest and Great Basin ...Interior Pac. Northwest & northern Great Basin... As the ridge builds quickly this weekend, enhanced flow aloft will develop along the eastern periphery as a weak trough moves south out of Canada. At the surface, a weak cold front should move south into the Great Basin, enhancing surface winds and the chance for isolated thunderstorms over parts of OR, NV, UT, and ID. Isolated critical fire-weather conditions could occur D3/Mon as the gusty winds and low RH spread through the northern Great Basin and Snake River Valley. Behind the front, dry northwesterly surface flow should continue through the first part of the week as the ridge aloft intensifies.

MD 1475 CONCERNING SEVERE POTENTIAL...WATCH POSSIBLE FOR PORTIONS OF NORTHERN WV INTO MD AND NORTHERN VA
Mesoscale Discussion 1475 NWS Storm Prediction Center Norman OK 0230 PM CDT Sat Jun 29 2024 Areas affected...portions of northern WV into MD and northern VA Concerning...Severe potential...Watch possible Valid 291930Z - 292100Z Probability of Watch Issuance...40 percent SUMMARY...Isolated strong storms may produce locally damaging gusts into early evening. Area is being monitored for possible watch issuance. DISCUSSION...Isolated thunderstorms are developing within weak to moderate instability and modest vertical shear. A narrow corridor may exist where more favorable shear overlaps with stronger instability and steep low-level lapse rates. A few strong to isolated severe storms capable of mainly damaging gusts (45-60 mph) will be possible into early evening. While spatial/temporal extent of the risk is expected to remain limited, a small severe thunderstorm watch is being considered. ..Leitman/Gleason.. 06/29/2024 ...Please see www.spc.noaa.gov for graphic product...
