Thunderstorms Tuesday for the Southern Plains and Lower Mississippi Valley
A weak area of low pressure is forecast to develop over northeastern Texas this morning or by early afternoon and lift northward. This will bring moisture northward into the Lower Mississippi Valley ahead of a cold front. Increasing shower and thunderstorm activity is expected ahead of the front as it moves southward across Texas, Arkansas, and Louisiana through the evening. Despite marginal instability, a few storms may be capable of producing hail and damaging winds. Overall, severe impacts should be limited.

A Look Ahead
As an area of low pressure moves into the Northeast on Sunday, precipitation that develops along and ahead of the system’s cold front will likely fall as snow or a mixture of snow/sleet/freezing rain. Model guidance is showing this wintry mix from eastern Oklahoma into the Ohio Valley, with snow further to the north. Exact locations and amounts are highly uncertain at this time and later forecasts will allow details to become more clear.
