(This evening through Friday night) Issued at 215 PM CDT Thu Jun 20 2024 Showers with isolated storms continue to move into the southern Panhandles from Tropical Storm Alberto. Most of these are fairly stable showers and the lightning threat is pretty minimal at this time. There may be a little uptick in lightning as we move into the later afternoon to early evening hours, with increased heating and instability. Overall, if showers enhance into storms, the main concern will be lightning, but we could have brief intense rain rates given the tropical moisture advection over the area and PWAT`s approaching 1.50". The southerly flow will shift more southwesterly into Friday. The moisture will shift more to the western Panhandles for Friday, but it`s possible that we don`t see any showers or storms at all, as it may stay isolated to eastern NM. Weber

(Saturday through next Wednesday) Issued at 215 PM CDT Thu Jun 20 2024 Upper level trough moving across the northern CONUS will help suppress the high over the southeast CONUS. This will help transition the overall flow to a more zonal flow. Temperatures will gradually rise, but the chances of showers and storms will be limited. As we move into Sunday the trough will be further to the east over the Great Lakes and that will help the zonal flow transition to more northwest flow as the high rebuilds over the Four Corners. This will lead to a decent chance of showers and storms on Sunday evening, as there is a more pronounced shortwave embedded in that flow. Monday looks pretty similar to Sunday, but a weaker shortwave so a lower probability of showers or storms. Tuesday and Wednesday will once again have a better shortwave and a more amplified ridge associated, so temperatures will be even warmer, RH values will be quite high for our area leading to heat index`s in the 100-108 range across most area, as well as more scattered storms.

&& .AVIATION... (18Z TAFS) Issued at 1056 AM CDT Thu Jun 20 2024 All the TAF Sites are VFR to start the 18 UTC TAF period. Scattered SHRA moving northwest could pass near or through any of the TAF sites this afternoon and evening, bringing a brief period of broken low ceilings, although confidence is too low to include in the TAF, even at KAMA, which has the highest chance. Guidance suggests that MVFR CIGS will develop at KAMA and KDHT early Friday morning, and not out of the question that KGUY could see low stratus as well. Southerly surface winds should pick up this afternoon becoming sustained around 14-20 kts for a time before diminishing this evening. && .PRELIMINARY POINT TEMPS/POPS...
