Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0316 AM CDT Wed Aug 21 2019 Valid 241200Z - 291200Z ...DISCUSSION... Strong northwest winds aloft will dive southeastward across the northern Rockies and into the Plains, with one or more leading waves affecting the northern Plains on Saturday/D4 and Sunday/D5 before the larger amplification occurs Tuesday/D7 into Wednesday/D8. These lead waves will interact with a plume of mid 60s F dewpoints over the Dakotas and western MN D4 and D5, with at least isolated severe hail possible. Mitigating severe coverage will be relatively cool air emanating out of a surface ridge to the east, suggesting storms may become elevated as they move east away from the deeply mixed air near the surface trough. That said, models differ on the timing of these waves, thus predictability is too low to introduce severe probabilities. During the D6-D8 time frame, more robust low-level moisture will be in place from NE toward the Upper Great Lakes, and winds aloft will increase over the northern Plains, Upper MS Valley and Great Lakes, suggesting severe potential. Though timing issues exist amongst the models, the general signal is for the upper winds to become nearly parallel to the cold front, with areas of damaging wind possible from the central and northern Plains to the Upper MS Valley and Midwest.

MD 1824 CONCERNING SEVERE THUNDERSTORM WATCH 608... FOR WESTERN/CENTRAL NE
Mesoscale Discussion 1824 NWS Storm Prediction Center Norman OK 0315 AM CDT Wed Aug 21 2019 Areas affected...Western/central NE Concerning...Severe Thunderstorm Watch 608... Valid 210815Z - 210945Z The severe weather threat for Severe Thunderstorm Watch 608 continues. SUMMARY...Some severe wind risk will continue with bow echo moving across western Nebraska. Gradual weakening is expected with time, and downstream watch issuance is unlikely. DISCUSSION...A bow echo is moving eastward out of the NE Panhandle as of 08Z, with increasingly disorganized elevated convection ongoing downstream into central NE. Relatively steep pressure rises and cold temperatures (falling into the 50s F) in the wake of the bow suggest a somewhat well-organized cold pool, though radar velocities indicate that the rear-inflow jet is not overly strong, and observed wind speeds (where available) have been subsevere over the last 1-2 hours. While the airmass immediately downstream of the bow likely remains strongly unstable (MUCAPE of around 3000 J/kg), convectively overturned air emanating out of western KS and also central NE is likely to erode this instability with time, resulting in a general weakening trend. Some severe wind risk will persist given the well-established cold pool, but a general decrease in the wind risk is expected with eastward extent. With these factors in mind, downstream watch issuance into central NE is unlikely. ..Dean/Edwards.. 08/21/2019 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...GID...LBF...

SPC 0730Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0215 AM CDT Wed Aug 21 2019 Valid 231200Z - 241200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FROM NORTH CAROLINA INTO SOUTHERN VIRGINIA... ...SUMMARY... Isolated severe wind gusts are possible Friday over parts of North Carolina and southern Virginia. ...Synopsis... An upper low will pivot northeast across the Canadian Maritimes, with a jet streak sweeping across New England and tail end near the Mid Atlantic. At the surface, high pressure will remain over the Great Lakes, with a cold front moving south toward the VA/NC border. A weak surface low is forecast to develop over eastern VA and NC near the front where 70s F dewpoints and heating will contribute to moderate destabilization. To the west, a leading shortwave trough will eject out of the Dakotas toward western Ontario as a broad upper jet noses into the northern High Plains Friday night. Dewpoints in the 60s F will exist over the Dakotas ahead of a dying front related to the leading wave, and will back westward toward MT by 12Z Saturday. Elsewhere, a loose east-west boundary will remain roughly from KY/TN into north TX, with bouts of mainly non-severe thunderstorms through the period. ...NC into southern VA... Strong heating of a moist air mass will occur south of the cold front approaching the VA/NC border late in the day. Forecast soundings indicate 2000-2500 J/kg MLCAPE developing despite poor midlevel lapse rates, though low-level lapse rates will become steep. With no capping present, the front will provide a focus for scattered storms, which may produce locally severe wind gusts as they propagate southeastward from VA into NC. Models are in good agreement depicting a relatively concentrated area of storms in this area. ...Northern High Plains... Elevated thunderstorms may be ongoing Friday morning over central ND in association with the departing shortwave trough, but will likely lose strength as lift wanes, and due to dry trajectories out of the surface high to the east. As cooling aloft arrives from the west, lapse rates as well as deep shear will increase, conditionally favoring elevated hail into Saturday morning over eastern MT. At this time, storm chances prior to 12Z Saturday appear too low to introduce severe probabilities. ..Jewell.. 08/21/2019 Read more

SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0143 AM CDT Wed Aug 21 2019 Valid 221200Z - 231200Z ...Synopsis... An upper-level shortwave trough will continue to move east-northeast across the northern Intermountain West tomorrow. An associated surface cold front will continue to move south and east into the Great Basin and through much of the northern Rockies and northern California. With a pre-frontal surface pressure trough running parallel and ahead of the cold front, the surface pressure gradient will strengthen across the Intermountain West along and ahead of the cold front. Elevated conditions are expected from northern Arizona/southern Nevada stretching northeastward into central Wyoming along/ahead of the surface cold front. Southwest-westerly sustained surface winds of 15-20 mph and RH values of 8-20% are likely to develop during tomorrow afternoon and evening across this area. High clouds may drift into northern Arizona, which could limit the southern extent of the current elevated area. Elevated conditions are also likely to develop across central/eastern portions of the Snake River Plain and vicinity tomorrow afternoon. The cold front will have passed through the area, but daytime heating should warm temperatures and mix the boundary layer enough to result in west-southwest winds of 15-25 mph and RH values of 15-20%. ..Nauslar.. 08/21/2019 ...Please see www.spc.noaa.gov/fire for graphic product...
