Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0206 AM CDT Sun Jul 14 2024 Valid 151200Z - 161200Z ...Synopsis... Isolated to widely scattered dry thunderstorms are expected again on Monday as a weak mid-level perturbation (currently off the CA coast) continues to translate to the north/northeast on the northwestern periphery of a de-amplifying upper ridge over the Four Corners. The diminishing ridge and weak nature of the offshore low will result in muted surface pressure gradients and generally benign winds away from convective outflows. A plume of 0.5 to 0.75 PWAT values is already in place across the Great Basin and central Rockies, and thunderstorms over the preceding days are not expected to appreciably moisten the lowest few kilometers or provide much wetting rainfall. This should maintain receptive fuels and favorable thermodynamic profiles for dry thunderstorms across a large swath of the Great Basin. Thunderstorm coverage may be higher across the central and northern Rockies, but higher PWAT values, lower LCLs, and higher MUCAPE values suggest the potential for wet thunderstorms should increase with eastward extent. ..Moore.. 07/14/2024 ...Please see www.spc.noaa.gov/fire for graphic product...

WW 528 SEVERE TSTM MN WI 140255Z - 140900Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 528 NWS Storm Prediction Center Norman OK 955 PM CDT Sat Jul 13 2024 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Central Minnesota Far West-Central Wisconsin * Effective this Saturday night and Sunday morning from 955 PM until 400 AM CDT. * Primary threats include... Scattered damaging winds likely with isolated significant gusts to 75 mph possible Isolated large hail events to 1.5 inches in diameter possible A tornado or two possible SUMMARY...A small bowing complex of thunderstorms should move southeastward this evening and overnight, posing a threat for mainly severe/damaging winds around 60-70 mph. Occasionally stronger gusts up to 75 mph appear possible, along with isolated large hail around 1-1.5 inches in diameter. The severe thunderstorm watch area is approximately along and 70 statute miles east and west of a line from 40 miles east northeast of Alexandria MN to 20 miles south southeast of Minneapolis MN. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU8). PRECAUTIONARY/PREPAREDNESS ACTIONS... REMEMBER...A Severe Thunderstorm Watch means conditions are favorable for severe thunderstorms in and close to the watch area. Persons in these areas should be on the lookout for threatening weather conditions and listen for later statements and possible warnings. Severe thunderstorms can and occasionally do produce tornadoes. && OTHER WATCH INFORMATION...CONTINUE...WW 522...WW 523...WW 524...WW 525...WW 526...WW 527... AVIATION...A few severe thunderstorms with hail surface and aloft to 1.5 inches. Extreme turbulence and surface wind gusts to 65 knots. A few cumulonimbi with maximum tops to 500. Mean storm motion vector 30035. ...Gleason Read more
