Double Dousing of Rain

14 Jan 2010, 12:34 pm

There is the potential for two major rain events within a weeks time.  The first rain event is just getting started across south Texas with light rain falling this morning.  Heavier rain and a few thunderstorms will develop tonight.  A month’s worth of rain or more could fall with some areas picking up close to 10″.


In anticipation of the soaking rain that will last for the better part of the weekend, the National Weather Service has issued a Flash Flood Watch for the Corpus Christi and Brownsville area.  The rain is being fueled by a potent ripple of low pressure in the upper atmosphere.  This low will move into northern Mexico tonight and form a surface low just off the coastal bend of Texas.  Texas won’t be the only one getting the deluge.  The Southeast will receive this rain over the weekend and eventually the Northeast may see a wintery mix in spots from this same storm Sunday night into Monday.  The big metropolitan areas of New York City and Philadelphia may be warm enough for rain at the onset but change to a light rain/snow mix Sunday night.  There is a degree of uncertainty with this storm so check back tomorrow for an update.


The second rain event comes later this weekend and it’s on target for southern California.  The weather will become increasingly unsettled for the western U.S.  With just a month until the 2010 Winter Olympics, Cypress Mountain Ski Resort in Vancouver, Canada was closed for a time because of poor conditions.  Rain and temperatures in the 40’s made it impossible to make snow.  Workers at Cypress Mountain stress, however, that the patchy green spots are on the lower slopes with the majority of the races scheduled on the upper slopes.


Rain should move into southern California Sunday and continue through next week with the potential for 3-6″.  Flooding and mudslides, especially in the recent burn areas, will be a threat.
