Southwest flow aloft is increasing as upper low nears the California coast: and several short waves out ahead of the low near Baja rotate east toward New Mexico. This flow will bring up existing sub-tropical moisture over northern Mexico, including some moisture from TS Vance, across the CWA Thursday. PWs approach one inch from the RG Valley east. Batted around a flood watch but decided not to issue one. The moisture, decent instability and slow storm movement could still create a few flooding storms.

One of the short waves rotating out of the California trough reaches New Mexico late FRIDAY afternoon and into the evening to spread another round of showers/storms to the area. PWs almost as high as Thursday's event, with sub-tropical jet approaching and drawing in moisture from the eastern Pacific. Shear environment looks better than Thursday, and along with modest CAPE values may be more conducive to some strong/severe storms. The negative is that the storms are not likely to start until late in the day.

SATURDAY (Halloween) looks to be a tweener day as the short wave exits the area and we await the the west coast upper low. Both GFS/ECMWF dampen the low as it approaches, but phasing it in with the Pac NW over the Great Basin SUNDAY. This looks to be a fast moving feature, though ECMWF somewhat slower. GFS moves it out by late Sunday night while the ECMWF lets it hang around until Monday afternoon. Showers/storms should start out west Sunday afternoon and spread east through the evening hours. Once again PWs approach or slightly exceed one inch, suggesting some flood potential. However mid-level storm motion winds of 30-50 mph may not allow for prolonged rain over any specific area.

Main Pacific cold front moves through late Sunday night with secondary colder front dropping out of the Great Basin to the CWA Monday night. High temps by Tuesday may remain in the 60s across the lowlands.

Low fire weather concerns will continue through the next several days as an unsettled weather pattern brings more rain chances to the region. Temperatures will run near normal through the weekend, while minimum RH values will be quite elevated -- dropping only into the 35 to 45 percent range in the lowlands, and higher values in the the mountains. Lighter low level winds will cause vent rates to suffer in parts of the Tularosa Basin today, and over the entire area on Friday.
