Forecasters: David Thede (NWS/GLD) and Bruce Entwistle (NWS/GLD)
A cold front has moved through the research area as of 15Z with a strong low level anticyclone moving southeast out of Wyomeing. Some cold core convective activity in the form of post-frontal showers or weak thunderstorms are possible in extreme northeast Colorado.
Stable conditions are expected through Wednesday with fast northwest flow aloft.
On Thursday the progs suggest a Pacific cold front will approach the area late in the day with a lee trough extending through eastern Colorado. Another strong northwest to southeast oriented jet is expected to approach, and this could provide enough shear for organized supercellular convection, but it is uncertain whether sufficient low- and mid-level moisture will be available for thunderstorm development.
