SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0459 PM CDT Sat Aug 05 2023 Valid 071200Z - 131200Z ...Southwest... Dry westerly flow across the northern Arizona and north/central New Mexico will continue to augment drying fuels on D3 - Monday and D4 - Tuesday. Moisture will attempt to move into far southern/south-central New Mexico Monday into Tuesday, which will limit the southward extent of lower relative humidity. The mid-level high will begin to build back in across the Four Corners Region from Tuesday onward, with decreasing wind and increasing temperatures. Pockets of Elevated fire weather concerns will be possible with afternoon relative humidity around 15-20 percent but breezes will be localized and remain below Critical criteria. A return of more appreciable monsoon moisture further north into northern Arizona/western New Mexico looks favorable by late in the period as the high builds with weak troughing off the west coast enhancing southerly moisture transport off the Gulf of California. ...Central Texas... Extremely hot and dry conditions continue to render extremely dry fuels across central/southwestern Texas. Elevated conditions are possible most each day of the extended period, with the limiting factor being widespread sustained winds at or above 15 mph. Even in the absence of winds, fuels and extremely hot and unstable conditions continue to foster increased fire behavior. A surface front sagging southward Sunday into early Monday will cool highs and bring increase in cloud cover and shower/thunderstorm potential across northern Texas near the Red River Valley. Mainly light rainfall is forecast within this region, which may not change the status of fuels considerably heading into increasing winds on Tuesday/Wednesday as a surface low develops across the Southern Plains. Afternoon relative humidity reductions to 15-20 percent and sustained winds 15-20 mph will be possible on Tuesday and Wednesday. 40 percent probabilities were introduced on these days with better confidence in the stronger winds overlapping continued hot/dry conditions. ..Thornton.. 08/05/2023 ...Please see www.spc.noaa.gov/fire for graphic product...

MD 1848 CONCERNING TORNADO WATCH 589... FOR NORTHWESTERN IOWA INTO ADJACENT AREAS OF SOUTH DAKOTA AND NEBRASKA
Mesoscale Discussion 1848 NWS Storm Prediction Center Norman OK 0502 PM CDT Sat Aug 05 2023 Areas affected...Northwestern Iowa into adjacent areas of South Dakota and Nebraska Concerning...Tornado Watch 589... Valid 052202Z - 060000Z The severe weather threat for Tornado Watch 589 continues. SUMMARY...The threat for a tornado or two continues across northwestern Iowa into adjacent areas of southeast South Dakota and northwest Nebraska. DISCUSSION...Thunderstorm activity over the mid-Missouri River Valley continues to be focused along a surface warm front noted in recent surface analysis. By most metrics, this convective intensity has been muted with modest reflectivity values, transient lightning pulses, and somewhat warm cloud top temperatures. However, cells continue to take on supercellular characteristics early on in their life cycle, and weak low to mid-level rotation is noted in KFSD velocity data. KFSD VWP observations well north of the warm front show 0-1 km SRH values near 200 m2/s2 where surface winds are easterly. This is likely an overestimate for the what cells are experiencing along the warm front (where winds are out of the southeast). But taken in context of the velocity trends suggests that SRH is likely sufficient to maintain a tornado threat for more robust cells that can become established prior to moving into a more stable air mass north/northeast of the warm front. ..Moore.. 08/05/2023 ...Please see www.spc.noaa.gov for graphic product...

Tropical Storm Eugene Forecast Discussion Number 2

2 years ago
Issued at 300 PM MDT Sat Aug 05 2023 444 WTPZ41 KNHC 052038 TCDEP1 Tropical Storm Eugene Discussion Number 2 NWS National Hurricane Center Miami FL EP062023 300 PM MDT Sat Aug 05 2023 This afternoon's satellite presentation of the system has improved, with a well-developed curved band in its eastern semicircle and a recent burst of deep convection with -75 Celsius cloud tops just east of the surface circulation. Based on this and a consensus of the objective intensity estimates from UW-CIMSS, the system is being upgraded to Tropical Storm Eugene, making it the fifth tropical storm of the eastern North Pacific hurricane season. Although dry mid-tropospheric air originating from mainland Mexico may be negatively affecting the cyclone's intensification rate, as indicated by the presence of a few arc clouds, a brief window of opportunity still exists for further strengthening during the next day or so. By mid-period, Eugene is expected to move over the cooler water west of the Baja California peninsula and enter a surrounding dry and stable marine-layer air mass. The NHC forecast calls for the cyclone to degenerate to a remnant low by 72 hours, or sooner, and dissipation in 5 days which is slightly below the Decay SHIPS statistical guidance, but close to the LGEM and the usually reliable intensity consensus guidance. The initial estimated motion is northwestward or 315/13 kt. The track forecast philosophy remains unchanged, and Eugene should move generally northwestward in the short term within the southeasterly mid-level steering flow provided by a subtropical ridge to the north. By 48 hours, the vertically shallow cyclone should turn toward the west-northwest in the lower boundary trade wind flow while a reduction in forward speed takes place, possibly meandering before dissipating next week. The updated NHC track forecast is very similar to the previous official forecast and lies near the various consensus models. Although the track forecast is currently off the southwestern coast of Mexico, enough uncertainty still exists that interests in the southern portion of the Baja California peninsula should monitor the progress of this system.

Hurricane Dora Forecast Discussion Number 22

2 years ago
Issued at 1100 AM HST Sat Aug 05 2023 000 WTPZ45 KNHC 052037 TCDEP5 Hurricane Dora Discussion Number 22 NWS National Hurricane Center Miami FL EP052023 1100 AM HST Sat Aug 05 2023 Dora has become significantly better organized over the past six hours, with a well-defined 15 n mi wide eye inside a cold central dense overcast. The various subjective and objective satellite intensity estimates are now in the 100-120 kt range, and the initial intensity is increased to 115 kt in best agreement with the subjective estimates from TAFB and SAB. As noted in the last several advisories, Dora continues moving westward along the southern side of a deep-layer ridge to the north. This ridge is expected to build westward for the next three days or so, which should induce a somewhat faster forward speed while it passes well south of Hawaii early next week. There has been little change to the track guidance since the last advisory, and the new forecast track is again almost identical to the old track. Dora is moving over sea surface temperatures near 27C, and it is currently in a light-shear environment. This is at least partly responsible for the current intensification. The intensity guidance suggests this round of intensification should be almost over, although there is some uncertainty in this since it underestimated how strong the storm would get today. Based on the current trends and the current guidance, the intensity forecast calls for some additional strengthening during the next 12 h, followed by some weakening. After 48 h, while Dora should remain over 27C sea surface temperatures and in light shear through 96 h, it is expected to encounter a drier environment and an area of upper-level convergence. These factors should lead to continued gradual weakening, with the caveat that there is a large spread in the guidance on how much weakening will occur. The early part of the intensity forecast follows the upper edge of the intensity guidance, while the 60-120 h portion is in best agreement with the SHIPS model.
