A storm system developing offshore of southern Texas will move gradually east across the northern Gulf of Mexico over the next few days, and this will bring a swath of moderate to locally heavy rain for portions of the drought stricken Gulf Coast states.

Given the very dry antecedent conditions, these rains will be very beneficial in nature and there may be locally a few inches of rain that falls.
Any flooding concerns should be minimal and generally confined to the more urbanized locations.
The clouds and rain will also keep temperatures rather cool, and many areas from southern Texas eastward across the Gulf Coast will see temperatures below normal.
Meanwhile, a cold front crossing the Pacific Northwest will advance east across the Northern Rockies by Tuesday before gradually stalling out over parts of the Intermountain West.
The front along with some intrusions of Pacific moisture will bring a threat for showers, including some accumulating snowfall for the higher elevations of the Washington Cascades and the Northern Rockies.
The higher peaks may see locally in excess of 6 inches of new snow by the middle of the week.
Some of this moisture will also be influenced by a developing area of low pressure offshore of California which will slowly drop southward and meander off the coast going through the middle of the week.
This will bring some light to moderate rainfall into California and may even bring a few inches of snow to the highest elevations of the Sierra Nevada.
Elsewhere, aside from a weak area of low pressure crossing portions of northern New England and bringing some light snowfall here early this week, the story for the remainder of the nation will be the very mild and dry weather.
Much of the nation is dominated by an airmass of Pacific origins, with all of the cold, Arctic air currently focused well to the north over central and northern Canada.
Over the next few days, very mild weather will continue across especially areas of the Intermountain West, the Central and Northern Plains, and the Midwest where temperatures will be as much as 15 to 25 degrees above normal. ■
Modified arctic air combined with a moisture-laden area of low pressure along the Gulf Coast will continue to allow for a broad area of winter weather impacts from the Lower Mississippi Valley to the Southeast today into early Saturday morning.
