AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GREAT FALLS MT 957 PM MDT Tue Jun 25 2013 .UPDATE... Occasional lightning strikes accompanied a band of showers/weak thunderstorms that moved through central Montana this evening, but instability has now weakened...thus no thunder expected overnight. A few showers will affect parts of central and southwest Montana through the overnight period. Although, the better chances for showers will be over the higher terrain of southwest Montana, especially after 06z/Wed. The NAM depicts a plume of high mid- level relative humidity values moving into this region between 06z and 12z/Wed which will likely coincide with the best chance for scattered showers. Otherwise, expect quiet conditions overnight with lows in the 50s and 40s for most areas. Uttech && .AVIATION... Updated 0354Z. A weak upper level disturbance is keeping the airmass unsettled with scattered showers. The airmass is quite dry and widespread low clouds are not expected. Brisk west winds will continue Wednesday and afternoon gusts should be expected across the region. VFR conditions will prevail through the next 24 hours. && .PREV DISCUSSION... /ISSUED 528 PM MDT Tue Jun 25 2013/ Tonight through Thursday...Southwest flow aloft continues to bring moisture and instability to the area. Convective activity is slow to develop this afternoon but a large plume of moisture is now moving into western Montana with scattered showers and thunderstorms developing. RUC analysis continues to show precipitation developing over the area this evening and development will be aided by a jet streak moving across the area. Have painted low pops across the county warning area until midnight. Any thunderstorms that develop will likely be high based with gusty winds being the main threat. Convective activity should generally end by midnight. Heights begin to rise Wednesday though isolated showers are possible in a swath across central Montana Wednesday morning due to the proximity of the jet streak. Heights continue to rise Wednesday afternoon through Thursday resulting in dry and warmer conditions. The strong westerly flow aloft Wednesday, combined with warmer temperatures, will allow the atmosphere to effectively mix down and gusty winds will result during the afternoon. Temperatures will be near seasonal averages Wednesday but will warm through the remainder of the week. Emanuel Thursday night through Tuesday...Medium range models remain in good agreement for the first few days of the forecast period. An upper level ridge over the western U.S. will strengthen over the northern Rockies for much warmer temperatures for Friday and Saturday. Model solutions diverge Saturday night as the GFS bring shortwave energy and an upper level jet through the northern Rockies for a slight chance of thunderstorms while the ECMWF keeps a dry and stable airmass in place. The upper wave depicted in the GFS will continue to affect central Montana through Sunday evening but the models come back into agreement by Monday as the ridge axis regresses into the Pacific northwest and puts Montana under a north to northwest flow aloft with unsettled but continued warm conditions into Tuesday. mpj && .PRELIMINARY POINT TEMPS/POPS...
