Updated at 1153 AM MDT Tue Jul 15 2025 - Available monsoonal moisture and daytime heating will lead to daily rounds of afternoon and evening showers and thunderstorms, mainly west of the Divide through Wednesday then across the Borderland for the end of the week. -Impacts from storms include periods of heavy rainfall with localized flash flooding, mainly small hail, gusty outflow winds, and areas blowing dust. - With the general summertime thunderstorm weather pattern, daily high temperatures top out very near seasonal averages. && .DISCUSSION... Issued at 1153 AM MDT Tue Jul 15 2025 SHORT TERM... Today, conditions are expected to be calmer across much of the CWA as compared to yesterday. Lower level, high pressure build up across southern NM will help limit early onset thunderstorm development. As we head into the afternoon, the high pressure will begin to give way to a small low level disturbance. The western portion of the CWA (Hidalgo, Grant, Sierra Counties) will see the greatest chance for scattered thunderstorms, especially along and west of the Black Range. Areal flooding will be a concern today for areas around the Trout Fire burn scar. Isolated thunderstorm development is also expected for the Sacramento Mts in Otero Co. Flooding remains a concern in the northern regions of the mountains, mainly along burn scars (Salt, South Fork, Seven Springs). Chances for severe weather is low due to lower levels of CAPE and weak wind shear with conditions being a bit more favorable over the western counties as previously mentioned. There will be some gusty outflow winds and blowing dust over Hidalgo and Luna counties is again a concern. Wednesday we will see more of a break regarding thunderstorm development. Higher pressure will move back in slightly, limiting most chances of thunderstorm development to the Sacramentos and Black Range. Temperatures will increase with the Metro seeing a max temp of 97F to 99F. The lower Rio Grande Valley will also see temperatures as high as 101F to 102F. LONG TERM... Thursday is when we will begin to see increased levels of atmospheric moisture begin to push into the state due to a low pressure system off the coast of Baja. Low level disturbances will begin to push out any remaining high pressure allowing for greater chances of development across the CWA. Heavy rainfall is expected with these storms. Areal flooding and flash flooding may occur with the most vulnerable places being burn scars and low lying areas. Friday is when we expect to see the greatest amount of precipitation. An upper level high will keep moisture capped over the state as lower level disturbances continue to aid in development. Heading into the weekend, conditions will begin to calm down as high pressure forms over the Texas panhandle. This will push much of that excess moisture to our west, mainly along the NM/AZ border. Chances of thunderstorm development will remain over the weekend, however the extent of coverage remains unclear with the deep moisture tap getting shut off. Dry air intruding into our CWA plus weak vertical forcing may hinder further development. Temperatures will remain constant, staying within the range of mid to upper 90s. Precipitation will aid in bringing temperatures down slightly across the CWA. Sunday is when we will begin to see temperatures increase as some drier air moves in with the lower Rio Grande Valley reaching 100-104F for the first part of the week. && .AVIATION... (18Z TAFS) Issued at 1153 AM MDT Tue Jul 15 2025 P6SM FEW-SCT100-120 SCT-BKN200-250 through much of the period. Expect scattered showers and thunderstorms to develop over the Gila region and then move onto the lowlands by late afternoon west of the Continental Divide. More outflow winds with gusts over 35KTS possible at KDMN which could produce some blowing dust and visibilities of 1-3SM, dust will also be an issue further west to the AZ border. An isolated storm over the Sacramento Mts can`t be ruled out between 18Z-22Z. Winds south to west AOB 12KTS to start period, but going into the overnight, west to northwest winds of 10-20G30KTS possible with strongest winds on eastern mountain slopes. && .FIRE WEATHER... Issued at 1153 AM MDT Tue Jul 15 2025 Modest low level moisture will remain around the region through the period with the main thunderstorm focus being west of the Divide through Wednesday then areawide going into the end of the week. Locally heavy rain will be possible with any storm as motion will be very slow. Min RH`s will be mainly in the 20s and 30s through Saturday before starting to drop back off early next week. Gusty outflow winds will be possible each afternoon, but the general wind flow is expected to be below 15 mph. && .PRELIMINARY POINT TEMPS/POPS...
