Stormy weather moving though our area now...
State College, PA) - A major and potentially costly storm is developing across the southern Plains. After dumping up to a foot of snow in parts of Colorado and New Mexico, the storm is now producing heavy snow across Kansas into eastern New Mexico. In some areas, it looks like a blizzard. Severe weather, including an outbreak of tornadoes, was unfolding across west and central Texas and Oklahoma this evening.
Our Severe Weather center will show all the watches and warnings associated with the storm as it continues to produce adverse weather across the southern Plains through tonight. The snow will continue to rage into the night as thunderstorms erupt across Texas into the lower Mississippi Valley. This is the type of situation, where tornadoes will develop due to strong shear present across Texas. In addition, the storms will produce damaging winds and large hail. The Southwest Regional News has more about the damaging storms and snow that fell over southern Rockies. The squall line that evolves out of the thunderstorms will move across the South Saturday into Saturday night with additional damaging wind gusts, large hail and tornadoes expected.
North of the severe weather, a snowstorm will continue across western Kansas, southwest into New Mexico. According to the Midwest Regional News story, the storm tapping into rich moisture from the Gulf of Mexico will dump up to 12 inches of snow from far northeastern New Mexico to southwestern Kansas into early tonight. Travel, both on the ground and in the air, will be hazardous in this region not only due to heavy, accumulating snow, but also because visibility will drop tremendously in blowing snow.
When the storm strengthens into a major nor'easter off the Northeast coast by the end of the weekend, a reappearance of heavy wet snow will be definite across far northern New England Sunday night into Monday. The East Regional News story discusses that chances for either a deluge of rain or a burying in a potentially record-challenging snowstorm in the rest of the interior Northeast will depend on the exact track of the storm.
Wherever wet snow falls, our Winter Weather Center is warning that the weight of snow, which will be loaded with moisture, could cause roofs to fail and may be responsible for power outages as power lines and tree limbs are brought down. The threat for flooding will quickly follow the storm's passage as temperatures moderate.
East of the area with the threat for a late-season snowstorm, the East Regional News story also states that a flooding rain will begin to spread over the eastern mid-Atlantic states and coastal parts of New England Sunday, with Monday's Boston Marathon possibly being adversely affected by the storm. Gale-force winds shifting to the north of the storm will blast the immediate shoreline and bring a threat of coastal flooding and beach erosion.

Statement as of 3:59 PM EDT on April 13, 2007
... Coastal Flood Watch in effect from Sunday afternoon through
Sunday evening...
The National Weather Service in Upton has issued a coastal Flood
Watch... which is in effect from Sunday afternoon through Sunday
evening.
A significant... possibly major... Nor'easter will affect the
region on Sunday and Sunday night. This storm will bring strong
northeast winds to the area on Sunday... causing water to pile up
in New York Harbor and along the South Shore of Long Island. The storm
will also coincide with a period of higher than normal Spring tides.
Minor coastal flooding will be possible during the high tide
cycle on Sunday morning. During the high tide cycle of Sunday
evening... only 1.5 to 2.5 feet of tidal surge will be needed to
produce moderate coastal flooding. The surge during this time is
expected to be above these levels... with preliminary surge
forecasts of around 3 feet. This would produce serious coastal
flooding similar to that experienced during the Halloween storm of
1991 and the superstorm of March 1993.
Although the coastal Flood Watch is posted only for the Sunday
evening high tide cycle at this time... there is a strong
possibility that the storm may stall south of Long Island... and coastal
flood watches and/or warnings may need to be extended into Monday
and Monday night. This scenario could result in significant
coastal flooding again with the high tide cycle Monday
morning... and major coastal flooding with the high tide on Monday
evening. Water levels Monday evening could potentially approach
levels last observed during the major Nor'easter of December 1992.
A coastal Flood Watch means that conditions favorable for
flooding are expected to develop. Coastal residents should be
alert for later statements or warnings... and take action to
protect property.
