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
