SHORT -TERM OUTLOOK:Increasing moisture and a slight chance of showers will today as southeast winds prevail and a weak disturbance moves across the southern Plains. Partly cloudy skies and mild weather will continue through tomorrow ahead of an advancing cold front.
NATIONAL OUTLOOK:This morning we find a surface low west of Fort Worth, with a warm front extending to the east ans southeast over southern Arkansas, Mississippi and the northern Gulf. Meanwhile, a weak cold front/dry line extends southwest from that low over west-central Texas and northern Mexico. Further west, a couple of cold fronts are moving ashore over the western third of the country with attached lows over Nevada and state. Finally, a slow-moving cold front stretches across the northern tier of states from Montana all the way to Quebec, with attached lows located over northern Wyoming, South Dakota and Quebec.
At the upper-levels, we continue in a mostly zonal west to east flow with a broad weak low pressure trough over eastern Canada and the Great Lakes, a short-wave trough moving east into the southern Plains and a low pressure trough over Washington and Oregon.
Mild conditions and a slight chance of showers or thunderstorms will be in our picture today. Tomorrow should bring partly cloudy skies and mild to warm conditions. Rain chances will re-appear on Wednesday as a cold front moves through the area, bringing cooler temperatures for the last half of the week. Rain chances will increase again this weekend as a surface low and upper-level disturbance combines with deep moisture levels to bring showers and thunderstorms to Southeast Texas.
Tropical development is not currently expected in the Atlantic Basin.
