Early this morning, some wrap-around rain showers were ongoing
across the plains associated with a positively leaning partially
closed low over central KS. Quite a bit of clouds were noted over
the lower elevations east of the mtns associated with this trough.
Otherwise, it was rather cool over the area as temps over the plains
were in the 40s and 50s with 30s in the valleys and 20s and 30s in
the mtns.
Today...
Precip over the plains this morning is expected to dissipate/move
out of the region towards sunrise, and clouds will gradually
dissipated from west to east as the morning progresses. Some patchy
fog cant be ruled out over the San Luis Valley and the Monument Hill
areas. Overall later this morning through afternoon should be very
nice day as mostly clear skies are anticipated and max temps will
most be in the 70s across the plains and 60s across the large
valleys. winds will generally be light, mainly from a northeasterly
direction over the plains later today. Winds will be light over the
mtns.
Tonight
Main concerns will be another round of cool temps over the San Luis
valley which will warrant another frost advisory for the San Luis
Valley. Most of the colder temps in the SLV will be over the central
and southern part of the valley. Otherwise, expect min temps over the
plains to be in the 40s.

.LONG TERM /THURSDAY THROUGH TUESDAY/...

Omega pattern will develop over the region later this week as two
slow moving closed mid level circulations, one over the east central
part of te country and the other over the SW CONUS, move slowly
east. This will keep warm conditions over the fcst area, with dry
conditions expected THU and only isold mtns activity on Friday.
By this weekend, a better chance of showers will occur over the
mountains, especially along the CONTDVD, as the closed circulation over
the SW moves towards the region.
Early next week, the closed low lifts northeast and opens up, and
this will bring some troughieness over the region. This will allow
for sctd/isold pops over the fcst area during the afternoon time
period. Temps should be around seasonable values. /Hodanish
