MD 1476 CONCERNING TORNADO WATCH 482... FOR CENTRAL/EASTERN PA
Mesoscale Discussion 1476 NWS Storm Prediction Center Norman OK 0309 PM CDT Sat Jun 29 2024 Areas affected...central/eastern PA Concerning...Tornado Watch 482... Valid 292009Z - 292145Z The severe weather threat for Tornado Watch 482 continues. SUMMARY...A risk for damaging gusts and a couple tornadoes will continue into early evening across central into eastern PA. DISCUSSION...A line of convection over central PA will continue to track toward the east at around 35-45 mph over the next few hours. This activity has a history or producing sporadic wind damaging across western and central PA this afternoon. The downstream airmass has warmed into the upper 80s amid near-70 F dewpoints. Lapse rates will remain poor, limiting stronger instability, though around 1000 J/kg MLCAPE is expected to spread eastward with time. Effective shear magnitudes around 40 kt, and enlarged, favorably curved low-level hodographs will continue supporting organized convection with a risk of damaging gusts and a couple of tornadoes. If current trends are maintained, an aerial watch extension may be needed across southeastern portions of WFO CTP as convection is expected to near the edge of Tornado Watch 482 by around 22z. The need for a downstream watch into portions of far southeast PA and NJ remains uncertain, but trends will be monitored. ..Leitman.. 06/29/2024 ...Please see www.spc.noaa.gov 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. 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...

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. 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.
