859 PM MST MON MAR 7 2016 UPPER LOW IS NOW OVER WESTERN NEBRASKA BUT THERE STILL REMAINS WRAP AROUND SHOWERS ACROSS PORTIONS OF THE PLAINS OF NORTHEAST COLORADO. THERE WILL BE A SLIGHT CHANCE FOR SNOW SHOWERS NEAR THE NEBRASKA BORDER AND IN THE HIGHER MOUNTAINS. AN UPPER LEVEL LOW OVER NORTHERN MEXICO AND A LOW OVER THE NORTHERN PLAINS WILL RESULT IN A QUIET DAY ACROSS THE AREA.
HIGH PRESSURE WILL REMAIN IN PLACE THROUGH TONIGHT.
Precip winding down in Norcal as upper low and main energy dig into Socal and Nrn Baja today. Well defined upper low center off the SFO Bay area coast dropping SSEwd along the Coast and on the backside of the upper trof today triggering scattered showers SW of our CWA. Most of tonight and Tuesday look dry (except for lingering flurries this evening at the higher elevations of the northern Sierra) as a positively-tilted ridge moves over the area and northerly surface flow develops. The upper ridge axis shifts Ewd on Wed allowing at least a chance of precip to sag as far S as I-80. Energy rotating around the GOA upper low will shift the next frontal precip band into Norcal Thu/Fri.

LATEST LINTON AND HETTINGER OBSERVATIONS ARE STILL SHOWING SOME DRY AIR IN THE LOWER LEVELS. AHEAD OF THE TROUGH EASTERLY FLOW CONTINUES OVER CENTRAL AND EASTERN NORTH DAKOTA. AS MID-UPPER LEVEL TROUGH LIFTS FROM THE CENTRAL ROCKIES INTO CENTRAL SOUTH DAKOTA.
At 2 PM on Monday, a strong short wave trough was moving northeast across northeast Colorado. Thunderstorm potential in the coming hours and days will revolve around the timing of individual short wave troughs that move quickly through the moist southwest flow aloft and bring periods of focused ascent and increased instability to the local area. The next good chance for thunderstorms comes with a well-organized short wave trough scheduled to cross the area late Tuesday morning into the afternoon hours.
401 PM CST MON MAR 7 2016 AS UPPER LEVEL FLOW CONTINUES ITS SWLY EVOLUTION AS SFC/UPPER LEVEL LOW PRESSURE CENTERS DEVELOPS ACROSS THE WRN U.

STILL DON/T SEE ANY TYPE OF FOCUSING MECHANISM AS HIGH PRESSURE REMAINS ACROSS THE SOUTHEAST. CONTINUED WITH THE WARMER SIZE OF GUIDANCE DUE TO THE DRY CONDITIONS AND DRY GROUND.
High pressure at the surface is wedging into the Commonwealth from the west thru the short term forecast period. Around the periphery of the high, convective elements were noted this morning, affecting our far northern/northwestern counties for a brief period. This will continue to be the case, as a slowly meandering upper low drifts across the lower Ohio valley, offering just enough lift in this area where moisture is pooling. This will offer a 20 pop or less (silent isolated mentions possible) thru tmrw, after which time, high pressure at both the surface and aloft suppresses any isolated chances still lingering. The upper low is effectively pinched off by high pressure aloft that is building in from the southeast and also from the north/west.
