Area Forecast Discussion National Weather Service El Paso Tx/Santa Teresa NM 228 PM MDT Sun Sep 17 2023 ...New SYNOPSIS, DISCUSSION, FIRE WEATHER... .SYNOPSIS... Issued at 108 PM MDT Sun Sep 17 2023 A few isolated to scattered showers and thunderstorms across the Borderland this afternoon will diminish overnight. Conditions will become mostly quiet on Monday with a few isolated thunderstorms mainly in the mountains. The next best chance for active weather areawide will be on Thursday with the winds becoming breezy toward the end of the week. The temperatures will warm to above the normal throughout the week for most of the area. && .DISCUSSION... Issued at 108 PM MDT Sun Sep 17 2023 Currently, the skies are partly cloudy with a few isolated showers and thunderstorms mainly across the mountains and the Bootheel area. For tonight, any remaining showers and thunderstorms should end by around midnight. The skies will be mostly clear with the winds near the surface below 15 mph and variable in direction. With that said, the low temperatures on Sunday morning will be above the normal for this time of the year. For Monday, drier air will begin to move in from the west. This will limit the amount of showers and thunderstorm development across the area. Any storms that do develop will be confined to mainly the mountain areas. The environment will be similar to that of this weekend; thus, one or two of these storms will be strong to maybe even severe in nature. Also, these storms will be isolated, so not expecting a lot of active weather as we may see with today's event. With mostly dry conditions and a quasi-ridge aloft, the high temperatures will be a few degrees warmer than what they will be this afternoon. For the rest of the period, mostly quiet weather is expected except for on Thursday. Tuesday and Wednesday will be storm-free as much drier air moves in with a shortwave trough across the Pacific Southwest and a ridge centered across northeastern Mexico. With dry conditions in store, the temperatures will be above the average on both days for much of the area. Overnight Wednesday, the shortwave trough across the Pacific Southwest will merge with a trough of low pressure across the Pacific Northwest while the ridge of high pressure shifts southeast of our area. With these two systems in place, moisture will be advected from the south into our area bringing a chance for showers and thunderstorms by early Thursday morning that will last throughout the day and the night as the low pressure trough rotates across the western part of the country. As of now, the precipitation will start along and west of the Continental Divide then spread through the entire area by midday Thursday. By the latter half of the week, the winds may become breezy especially on Friday as a lee cyclone develops across eastern Colorado and the low pressure trough passes to the far north of our area. Otherwise, the weather conditions for the rest of the forecast period will be quiet with temperatures continuing to be above the normal for most of the area except across the Gila Region and some areas west of the Continental Divide. && .AVIATION... (18Z TAFS) Issued at 1125 AM MDT Sun Sep 17 2023 VFR conditions are expected through the period across all of the TAF sites with CIG FEW070-BKN250. There will be periods of some SKC later in the period. The winds will be generally light with some gustiness of up to 20 kts off and on early in the period mainly across KDMN. However, gusty winds could occur across the rest of the sites until the sun sets. There will be SH and TS across Borderland this afternoon and evening. Not mentioned in the TAFS, but will amend should any SH or TS develop or move near or over any of the terminals. There will be no reduction in the VSBY across the runways. && .FIRE WEATHER... Issued at 108 PM MDT Sun Sep 17 2023 Some moisture will be in place this afternoon and evening that will aide in the development of a few showers and thunderstorms. Showers and thunderstorms may continue at least until midnight. Tonight recovery will be good to excellent. For Monday, drier air will begin to move in decreasing the storm chances across the area. Any storms that do develop will be confined to the mountains. The 20ft winds will be light and the temperatures above the normal for most lowland areas and vice versa in mountains. Monday overnight recovery will be fair to excellent. For Tuesday, more dry air will be in place with no storm chances in sight on that day. The 20ft winds will be mostly light and the temperatures above the average. Tuesday night recovery will be fair to good. For the rest of the period, mostly dry conditions are expected except on Thursday where there is a chance for showers and thunderstorms lasting through overnight hours. The winds will be light on Wednesday, but will become breezy toward the end of the week and the temperatures on the warm side across across much of the zones. With that being said, there will be no fire weather concerns on Monday, but elevated conditions for a couple zones on Tuesday. The min RHs on Monday will be between 18 and 26% in the lowlands and between 30 and 50% in the mountains. The min RHs on Tuesday will be below 20% in the lowlands and between 20 and 30% in the mountains. The ventilation rates will be poor to very good on Monday then good to excellent on Tuesday. && .PRELIMINARY POINT TEMPS/POPS...
