Area forecast discussion, Jul 2, 2:26 PM CST, 2 hours 7 minutes before
Area Forecast Discussion National Weather Service Amarillo TX 326 PM CDT Thu Jul 2 2020 .SHORT TERM...Tonight through Friday Night... Deeper moisture axis extending from the SW to NE corner of the Panhandles today will shift a bit to the far WRN and NW Panhandles and ERN NM by Friday morning. Weak H5 ridge axis (w/ 590-592 DM heights) will transition from just east of the CWA to just west of the CWA through Fri. Two separate small disturbances moving NE up the west side of the ridge (One over AMA and another one in ERN NM) are helping to trigger isolated to scattered convection along the aforementioned moisture band and an increase in coverage is expected over the next hour or two. Lack of shear will limit SVR potential, but a couple pulse type severe storms are possible with MLCAPE of 1000-1500 j/kg and DCAPE of 1400-1800. Storms will dissipate with loss of heating by late evening given weak synoptic support. Disturbances will make there way more from the NW on Friday as the H5 ridge axis slides west. This will provide another chance for thunderstorms, perhaps with a bit later start on Friday based on S/WV timing. Again, weak deep layer shear will strongly limit severe potential, and warming H5 temps will also weaken mid level lapse rates even more. This will also limit CAPE to perhaps less than 1000 j/kg. That said, the favorable upper level patter with ridge axis to the west and favorable moisture profiles will still warrant ISO to SCT POPs favoring the NW half of the area for greatest chances in the late afternoon and evening. Gittinger && .LONG TERM...Saturday through Wednesday... Precip chances continue through the weekend and into the beginning of next week and maybe longer. The midlevel ridge continues to retrograde and weaken through the extended. Saturday through Monday the models agree that there are chances of precip as shortwaves continue to cruise around the edge of the high pressure. Still to hard to say at this point where storms will affect fireworks for the 4th. Forecast soundings aren't too excited for severe weather potential, so most storms will be pulse type with some gusty winds possible. By next week, models start differing on opinion of what is going to happen. Some models for Monday appear to have an MCS left over that could clip our eastern sections during the day. Others are a bit faster with it and move it out by early morning. Have added in the possibility of precip for the day. The disagreements continue into the middle of next week as some models want to keep us dry and others generate storms. This will all depend on the position of the high pressure bubble. If it moves far enough west we can be in northwest flow and see storms. If it stays closer to the Panhandles, we may be in drier northeast flow aloft. Beat && .PRELIMINARY POINT TEMPS/POPS...
