Issued at 228 AM MDT Fri Jun 28 2024 Today will we see less activity across our area with the possibility of a few showers and thunderstorms in the mountains and the Bootheel area. The chances for showers and thunderstorms will gradually increase this weekend and through the first half of next week.

Issued at 228 AM MDT Fri Jun 28 2024 Currently, there are a few light showers across the area. These showers will continue to dissipate throughout the early morning. The skies are mostly cloudy, the temperatures are on the mild side with the winds light to breezy. For today, conditions will be a little more settled as a flat ridge of high pressure centers across the border of LA/AK/TX. The atmosphere will continue to be humid with dew point temperatures mainly in the 40s across most of the area with some mountain areas in the 50s. The PWAT values will be above the climatological average, but not as high as they were yesterday. However, with daytime heating, a few storms will develop especially in the mountains and the southern Bootheel area. The CAMs are suggesting that these storms begin to develop around 1 pm and end before midnight. These storms will be non- severe in nature with the main impacts heavy rainfall that could lead to isolated flash flooding, frequent lightning and strong gusty winds along out flow boundaries. The high temperatures in the lowlands this afternoon will be warmer than what they were yesterday afternoon. This will be due to few storm coverages. The temperatures for EL Paso and the Lower Valley will be at or near Heat Advisory criteria; thus, an advisory is effect for the mentioned areas. For tonight, any remaining storms as mentioned before should diminish by around midnight. There will still be some lingering clouds with the winds light to breezy. With that being said, there low temperatures on Saturday morning will be above the normal for this time of the year. For the rest of the period, active weather conditions will persist with triple digit heat for most lowland areas. By Saturday, the upper level ridge will amplify across the South Plains while its center moves across north-central Texas, and as it does, there will be a chance for showers and thunderstorms mainly across areas west of the Rio Grande. The temperatures especially in the lowlands will be definitely in the Heat Advisory criteria. Because of that, a Heat Advisory continues for El Paso and the Lower Valley, and has been included for the Dona Ana, Luna Counties and the Tularosa Basin for Saturday. The temperatures by then will be between 103 and 108 degrees, which will be the warmest of the weekend. By Sunday, the ridge will expand while steering the storms mainly into portions of eastern Arizona while edging across the Continental Divide. By the first half of next week, the expanse ridge will maneuver from across the South Plains and the Southeast. The further east it goes, the better chance we will see areawide storm coverage. Also, there will be a few shortwave troughs moving mainly to our north, which will enhance active weather across our area. Toward the end of next week an upper level ridge will build in from off the Pacific West, which will bring drier air to our area while limiting our storm chances by then. However, storm chances will not be automatically shut off as we will see storm developments from residual moisture and diurnal heating. The temperatures next week will still be hot with some lowlands still in the triple digits, but not as hot as they were last week and parts of this week.

&& .AVIATION... (06Z TAFS) Issued at 1126 PM MDT Thu Jun 27 2024 Most of tonight`s thunderstorms have died off, but we still have lot of clouds so we can expect mid and high ceilings for most of tonight. Skies will be less cloudy Friday morning, but we will likely see clouds build again on Friday afternoon. Right now I do think we will see some thunderstorms Friday afternoon, but they will not be as numerous as today`s storms and will be most common in area mountains. Winds tonight will be light from the west or northwest. During the day on Friday, the winds won`t pick up much, but again like today and yesterday, we could see some gusty outflow boundaries that can move well off from their parent thunderstorms. If gusty outflow boundaries develop tomorrow, we can amend TAF`s to account for the winds. && .FIRE WEATHER...

Issued at 228 AM MDT Fri Jun 28 2024 Today will not be as active as the past couple of days; however, there will still be a chance for showers and thunderstorms mainly in the mountains and Bootheel area. The main threat from these storms will be heavy rain and gusty winds. Also, can`t rule out an isolated thunderstorm or two across the lowlands west of the Rio Grande. The 20ft winds will be light to breezy and temperatures above the normal. Tonight recovery will be fair to good. Storm that linger from the day will diminish by around midnight. For Saturday, moisture will be limited especially across the lowlands. Chances for showers and thunderstorms will continue mainly west of the Rio Grande and in the mountains. The 20ft winds will be light to breeze with the temperatures above the average. Saturday overnight recovery will be good to excellent. For the rest of the period, there will be daily chances for showers and thunderstorms with breezy afternoon winds and at and above average temperatures. With that said, there will be no fire weather concerns across the entire zones throughout the period. The min RHs today will be between 18 and 24% in the lowlands and between 25 and 40% in the mountains. The min RHs on Saturday will decrease 2 to 4% in the lowlands and increase 1 to 2% in the mountains. The ventilation rates will be poor to very good today then poor to excellent on Saturday.
