DISCUSSION...Isolated strong to severe thunderstorms have developed this morning within strong ascent associated with an upper shortwave trough now ejecting east/northeast across western WY. The 12z RAOB from RIW showed very steep midlevel lapse rates and cold temperatures aloft amid increasing south/southwesterly mid/upper level flow. This vertical wind profile will maintain elongated/straight hodographs as the system continues to progress east/northeast into early afternoon. This environment will remain favorable for marginally severe hail over the next few hours. As stronger heating occurs with eastward extent, steepening low-level lapse rates and only modest boundary layer moisture may foster isolated strong gusts as well. Given limited coverage and overall marginal nature of the severe risk over the next few hours, a watch is not expected. ..Leitman/Guyer.. 08/26/2024 ...Please see www.spc.noaa.gov for graphic product...

Hurricane Gilma Forecast Discussion Number 34

1 year ago
Issued at 500 AM HST Mon Aug 26 2024 000 WTPZ42 KNHC 261459 TCDEP2 Hurricane Gilma Discussion Number 34 NWS National Hurricane Center Miami FL EP072024 500 AM HST Mon Aug 26 2024 Gilma still has a well-defined eye, seen on GOES-18 infrared and proxy-vis satellite imagery. The latest subjective intensity estimates are T-4.5/77 kt from TAFB and T-5.0/90 kt from SAB. Recent objective intensity estimates from UW-CIMSS such as the ADT and DPRINT are in the 80 to 85 kt range. However, during the last couple of hours, the eye has warmed and the cloud tops in the eyewall have cooled, so the initial intensity is increased to 90 kt, in best agreement with the SAB Dvorak intensity estimate. Gilma is likely currently experiencing 10 to 15 kt of westerly wind shear as it continues moving near and parallel to the 26C SST isotherm. Fluctuations in intensity appear possible for the next 12 h. Beyond 12 to 18 h, the westerly shear is forecast to increase to the 15 to 20 kt range, and the SSTs are forecast to decrease slightly along the path beyond 36 h. These factors, along with the relatively dry, stable environmental air mass that Gilma will be traversing for the remainder of its lifetime, are expected to lead to continued steady weakening. The NHC intensity forecast is a bit higher than the previous official forecast at hour 12, and then is similar to the previous official forecast. The NHC forecast is near the middle of the intensity guidance envelope. Gilma's initial motion is estimated to be westward, or 275/7 kt as it continues moving along the southern periphery of a mid-tropospheric subtropical ridge. The models continue to be in good cross-track agreement that the west to west-northwestward motion will continue, although there are still some along-track differences in the guidance. The new NHC forecast lies very close to, but perhaps a touch to the south of the previous official forecast. This forecast is close to the HCCA and TCVE consensus aids.

Although some weakening is forecast during the next few days, Gilma is still expected to be a hurricane when it reaches the central Pacific basin on Tuesday. Hurricane-force winds extend outward up to 15 miles (30 km) from the center and tropical-storm-force winds extend outward up to 80 miles (130 km). The estimated minimum central pressure is 974 mb (28.77 inches).

Tropical Storm Hector Forecast Discussion Number 4

1 year ago
Issued at 500 AM HST Mon Aug 26 2024 000 WTPZ43 KNHC 261438 TCDEP3 Tropical Storm Hector Discussion Number 4 NWS National Hurricane Center Miami FL EP082024 500 AM HST Mon Aug 26 2024 Microwave imagery continues to show evidence of northerly shear over the cyclone, with the mid-level center displaced a little to the south of the surface center. However, the overall cloud pattern appears to be slightly better organized than it was yesterday with some evidence of banding features over the eastern portion of the circulation. The advisory intensity has been increased a bit, to 45 kt, in agreement with subjective Dvorak Current Intensity Numbers from TAFB and SAB. Center fixes from geostationary and microwave imagery give a westward motion at around 270/9 kt. A weak low- to mid-level ridge is currently situated to the north of Hector, and the global models suggest that the ridge will build a little in a few days. The track guidance calls for a west-northwestward to westward heading with a slight increase in forward speed for the next 3-5 days. The official forecast is similar to the previous one and follows the dynamical model consensus predictions. Although the vertical shear is not forecast to be very strong, Hector is expected to traverse marginal SSTs for the next few days while it moves over or near the oceanic wake of Hurricane Gilma. Also, the global models show the system encountering increasingly dry air at low- to mid-levels. The intensity guidance does not call for much additional strengthening and the official forecast is at the high end of the model predictions. With the expected less favorable environment, a weakening trend is likely to begin in a couple of days. Simulated satellite imagery from the ECMWF and GFS models show little or no deep convection associated with Hector by the end of the forecast period, so the official forecast calls for the system to become a remnant low at that time.
