A persistent area of low pressure and warm front have set up over the Gulf of Mexico southeast of Texas and continue to bring elevated winds and seas to the western Gulf. Seas will range 6-9 feet along the southeast Texas coast. Winds 20-25 knots with gusts in excess of 30 knots are expected. Conditions are forecast to relax Tuesday morning before intensifying again Tuesday evening as the front begins to move eastward.

Thunderstorms across Arizona on Tuesday
An upper level trough will track across the Four Corners region on Tuesday. At the surface, strong daytime heating combined with plentiful low level moisture will allow instability to build. With lift provided by the trough, scattered showers and thunderstorms are expected to develop during the afternoon. A few storms could become strong to severe; damaging winds and hail will be the primary hazards with the stronger storms. These storms will track northeastward throughout the afternoon and evening toward northern New Mexico and diminish after sunset.

Snow Tuesday and Wednesday across Northern Maine
An area of low pressure will move southeastward into the Northeast  on Tuesday. As this occurs, the system will intensify during the overnight hours and begin to track northward. While this low strengthens, cold air on the northwestern periphery of the low will be brought southward into northern Maine and the Canadian Maritimes. With ample moisture and cold air in place, any precipitation that develops will be in the form of snow. Snow will begin from south to north starting late Tuesday and continuing into Wednesday evening. Snowfall amounts will range 3-6 inches across the lower elevations with amounts of 6-12 inches across the higher elevations.
