Area Forecast Discussion National Weather Service El Paso Tx/Santa Teresa NM 252 PM MDT SAT AUG 27 2016 .SYNOPSIS... Moisture and sunlight will continue to combine for scatteredthunderstorms tonight through at least Wednesday. Our high temperatures will continue to be below normal because of all the clouds and rain through the end of the week. && .DISCUSSION... Moisture and rain chances are on the increase and will continue for most of the coming week. Currently an upper level ridge well to our east and a weak upper level trough just to our west continue to pull moisture up out of Mexico. This morning's precipitable water value was just over 1.2 inches which is pretty good. With all the moisture and the weak trough just to our west we will see scattered evening thunderstorms tonight. The trough will be slow to dissipate so on Sunday we will again see scattered thunderstorms across the area. As the moisture continues to flow into the area we will see an increased threat for heavy rain and flash flooding. By the first of the week the upper trough will be gone, but we will still see lots of moisture flowing into the region. On Tuesday we will see our precipitable water values continue to rise to around 1.50 inches. With all the moisture in place we will see lots of clouds which will keep our temperatures well below normal. It will be a little bit of a challenge to fire off storms as, at the moment, there is not a clear trigger, but if storms are able to fire off they will be very efficient rain producers and could lead to some flash flooding. We will have to keep an eye on this potential in the days to come. By Thursday we will see a slight reduction in our moisture flow as the upper level ridge noses in from the east, but it won't last long as it almost immediately builds back east and allows for another surge or moisture in the area for next weekend. High temperatures will be pretty nice for the next seven days. Highs on Sunday will run a few degree below normal, then highs on Monday and Tuesday will be running 5 to 10 degrees below normal because of all the clouds and moisture. That means on Tuesday lowland highs could top out around 80 degrees. For the middle part of next week we will still have plenty of moisture and clouds around so our highs will still be running around 5 degrees below normal. Finally by the end of the week with slightly drier conditions so we will see our highs back to seasonal normals. && .AVIATION...Valid 28/00Z-29/00Z. P6SM FEW-SCT080-100 SCT-BKN150-200 thru pd with sct to nmrs mountain and sct lowland 1-3SM TSRA BKN040-060 mainly thru 06Z and after 17Z. Wind gusts to 40kts with thunderstorms...otherwise E to SE winds east of divide and W to NW west of divide AOB 12kts through 15Z then generally becoming easterly. && .FIRE WEATHER... A moderate low level easterly flow will be developing over the region over the next couple of days which will keep deep moisture in place. Scattered to numerous showers and thunderstorms are expected through midweek with temperatures dropping to slightly below normal due to the precipitation and expected cloud cover. Winds out of the east may occasionally be gusty over 20 mph but relative humidities will remain high...generally above 30 percent during this period. Vent rates however will be fair to good due to weak winds aloft. && .PRELIMINARY POINT TEMPS/POPS...
