Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1219 PM CDT Fri Jul 15 2022 Valid 161200Z - 171200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS CENTERED ACROSS THE CENTRAL PLAINS AREA... ...SUMMARY... Isolated severe thunderstorms are possible over the central Plains vicinity on Saturday. ...Synopsis... A relatively stagnant upper flow regime will persist across the U.S. Saturday, as a ridge remains dominant across the western and south-central states. Meanwhile, a trough will shift slowly eastward across western Canada and the Pacific Northwest, while a second trough over eastern North America continues making gradual eastward progress. Within the northwesterly flow between the western ridge and eastern trough, a series of vorticity maxima -- loosely functioning as a broader-scale short-wave trough -- will move southeastward out of the northern Plains and across the Upper Midwest through the period. At the surface, a cold front will move slowly across the Pacific Northwest, while a second/weaker front sags slowly southeastward across the Midwest and central Plains. ...Central High Plains to northern Missouri... Scattered showers and thunderstorms are forecast to be ongoing at the start of the period across portions of the northern and central Plains, with lingering convection and associated boundaries a complicating factor with respect to storm evolution/severe potential later in the day Saturday. While limited severe risk may linger across the Dakotas and Minnesota during the day, uncertainty prevails, precluding any severe-weather probabilities across this region in this update. From a larger-scale perspective, a surface front progged to extend east-to-west across the central Plains will be a focus for convective development. Isolated storms may initially develop across the central High Plains, while warm advection to the cool side of the boundary also suggests late afternoon storm development, as daytime heating contributes to a corridor of moderate destabilization. As a south-southwesterly low-level jet develops during the evening, isolated storms moving eastward across the High Plains may interact/congeal with convection farther east, potentially yielding an eastward-/southeastward-moving MCS across Kansas. While this scenario remains uncertain, the strengthening low-level jet beneath 40 kt west-northwesterly mid-level flow suggests this potential. In any case, gusty/locally damaging winds will be possible from afternoon into the overnight hours, with any stronger storms. ..Goss.. 07/15/2022 Read more

Mesoscale Discussion 1486 NWS Storm Prediction Center Norman OK 1221 PM CDT Fri Jul 15 2022 Areas affected...Parts of western into central Montana Concerning...Severe potential...Watch likely Valid 151721Z - 151915Z Probability of Watch Issuance...80 percent SUMMARY...A developing cluster of thunderstorms is expected to intensify and become better organized east of the Continental Divide. This may be accompanied by a developing swath of strong to severe wind gusts across and south of the Great Falls vicinity into central Montana (north through south of Lewistown) by 2-4 PM MDT. DISCUSSION...Downstream of one notable short wave perturbation progressing northeast of the Oregon Cascades, forcing for ascent has supported a sustained cluster of thunderstorms now spreading into and across the Continental Divide vicinity of western Montana. This activity appears to be focused near the nose of a 40-50 kt jet streak around 500 mb, with associated momentum contributing to a current forward propagation up to 40-45 kt. As forcing for ascent spread east of the higher terrain into areas near and south of the Great Falls vicinity within the next few hours, the environment appears likely to become increasingly conducive to renewed, intensifying thunderstorm development along an associated strengthening surface cold pool. In advance of the cold pool, forecast soundings suggest that further insolation will contribute to a seasonably warm and well-mixed boundary layer, including large surface temperature/dew point spreads up to around 40 F, but also characterized by CAPE on the order of 1000-1500 J/kg. Coupled with strengthening deep-layer shear, the evolution of an increasingly organized convective system seems possible, accompanied by increasing potential to produce strong to severe wind gusts while spreading into central Montana by 20-22Z. ..Kerr/Hart.. 07/15/2022 ...Please see www.spc.noaa.gov for graphic product...

SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1107 AM CDT Fri Jul 15 2022 Valid 151700Z - 161200Z The forecast remains unchanged. See the previous discussion for greater details. ..Wendt.. 07/15/2022 .PREV DISCUSSION... /ISSUED 0157 AM CDT Fri Jul 15 2022/ ...Synopsis... Across the western US, the mid-level flow pattern will remain dominated by a prominent anticyclone centered over the Southwest and southern High Plains. To the west of the ridge, a Pacific trough will move shoreward, bolstering mid-level southwesterly flow across the Cascades and northern Rockies. Beneath the ridge, a strong monsoonal surge will support scattered to widespread thunderstorms across the Southwest. Meanwhile, very warm and dry conditions are expected across the southern and central High Plains with temperatures exceeding 100F. ...Northern Great Basin... Modest southwesterly flow along the periphery of the ridge will support dry downslope flow off the Sierra across portions of northern NV, southeastern OR and eastern ID. Surface RH below 15% and winds near 15 mph will support elevated fire weather concerns given area fuel ERC values above the 90th percentile. Winds should gradually weaken overnight as the shortwave and stronger flow aloft move quickly northeastward. To the south and east, monsoonal moisture will support scattered thunderstorms across portions of central and northeastern NV. Along the northwestern fringe of the monsoonal plume, model soundings show initially dry sub-cloud layers greater than 2km deep supporting dry strikes over receptive fuels. Storm coverage and PWATs are forecast to gradually increase through the day, supporting wetter storms. However, the potential for a few drier strikes initially within receptive fuels necessitates continuation of the IsoDryT area across north/northeastern NV. ...Southwest KS and the Panhandles... Beneath the center of a strong and sustained mid-level anticyclone, a very warm airmass should develop across portions of the southern and central High Plains this afternoon. Low-level southerly flow bolstered by a weak lee trough/decaying cold front may support gusty winds to 15-25 mph coincident with surface RH below 20%. Ongoing drought and excessive heat (temps greater than 100F) will favor curing of short-hour fuels and the possibility of Elevated fire weather conditions. ...Southern Cascades... A gradual increase in low-level westerly flow is forecast today as mid and upper-level winds strengthen with the passing trough. Hi-res guidance indicates at least localized potential for winds greater than 15 mph through terrain gaps and in the immediate lee of the southern Cascades. Dry and warm conditions with humidity below 30% may coincide with these gustier winds, supporting locally elevated fire weather conditions across portions of OR. However, uncertainty on the areal coverage of sustained elevated fire weather conditions remains high, precluding any Elevated delineations. ...Please see www.spc.noaa.gov/fire for graphic product...

Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1103 AM CDT Fri Jul 15 2022 Valid 151630Z - 161200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM CENTRAL MONTANA INTO WESTERN NORTH DAKOTA... ...SUMMARY... Scattered strong to severe storms, including a risk of damaging winds and hail, will be possible across parts of the northern Rockies and High Plains today and tonight. ...MT/ND... Morning water vapor imagery shows a well-defined shortwave trough moving across eastern OR. This feature and its associated mid-level speed max will track across ID into MT this afternoon. Large-scale lift ahead of the trough is already resulting in scattered thunderstorms over the mountains of western MT, which will spread eastward into central/eastern MT this afternoon and evening. Hot surface temperatures in the 90s or low 100s are expected, yielding a deeply mixed boundary layer with 500-1000 J/kg of MLCAPE. This will support high-based convection capable of locally damaging wind gusts. This activity will likely spread into western ND after dark. Winds aloft weaken with southward extent, but at least isolated strong to severe wind gusts will be possible into parts of northern/eastern WY and western NE/SD this afternoon. ..Hart/Kerr.. 07/15/2022 Read more
