FTB 05-14-2016: A Great Start To The Weekend

NO FLOOD THREAT IS FORECAST.

Colorado remains downstream of a weak upper-level ridge. Though the ridge may be weak, it is still a ridge, and will cause overall downward motion in the mid-levels of the atmosphere today. Meanwhile, as shown nicely in the visible satellite image below, a low cloud deck has setup shop below about 8,000 feet east of the Continental Divide. This is courtesy of the shallow, moist cool front passage yesterday. The low cloud deck will slowly erode, but will limit how much heating will occur under its footprint. This will leave most of eastern Colorado with below normal temperatures.

The best chances for rainfall today will be in the southern part of the state. As the Southeast Mountains, Raton Ridge break out of the cloud deck, there will be enough moisture and instability to kick up at least an isolated shower and even a weak thunderstorm. However, rain rates will be far below levels required for flooding. Thus, no flood threat is expected today.

Looking ahead, active weather will return to our state late Sunday, and continue into Monday.
