A trough of low pressure at the surface will deepen today near the Colorado border as an upper level disturbance crosses the Rockies and moves out into the Central High Plains. Based on the mixing depth expected again today and highs yesterday will favor highs several degrees warmer than latest guidance. As this system crosses into the Northern Plains the surface lee trough will shift east into far western Kansas.
Surface and low level ridging over the mid-Atlantic seaboard are allowing for easterly flow, returning some warmer, moister air from the Atlantic. We're also seeing the front pushing the gradient of warmer temperatures and higher dewpoints to the north. Storms will initiate today ahead of and along the warm front, increasing chances for showers and thunderstorms offshore and along the coasline.

water vapor imagery showing a deep upper closed low across the cntrl Great Lakes region with large scale upper ridging in place across the American West. Fcst models have been in excellent agreement that the bulk of this activity will remain east of the KC Metro as the Great Lakes closed low slowly nudges east with time. models agree that strong high pressure will begin building south across the upper Miss Rvr Vly.

1114 AM CST TUE FEB 9 2016 Upper-level troughing will pervade from the Great Lakes through the eastern CONUS this week and into the weekend, resulting in chilly but mainly dry conditions throughout the CWA. Fluctuations in the strength and westward extent of the upper trough will allow highs to vary from the upper 20s to the middle 40s this week, and will also be moderated by cloud cover from weak, passing waves dropping down the back side of the upper trough. Broad, weak lift associated with the right entrance region of an upper jet streak will combine with pacific moisture rounding the ridge across the western U.
