The Storm Report Blog For December 29, 2012

Left Map Analysis: Looking at the Satellite Image from 10AM on Friday December 28th, we can note that our new developing low is starting to take shape in the Northeast part of Oklahoma, this low will track towards the east-northeast over time. The wrap around moisture with this system will again support the chance of seeing snowfall in some regions and also heavy rain in the Mississippi area is likely ahead of the warm front along with a squall line along the cold front further south.

Right Map Analysis: The center of the low is in Eastern Oklahoma and will begin to push towards the Northeast over the next 24hrs and be situated near the Memphis Tennessee area and then by the 29th it will be up along the Mid-Atlantic Region. The rainfall will spread from Eastern Texas through the Gulf Coast region and then into the Carolina’s by the 29th.  The region in light pink is our area of concern where the rain will mix with freezing rain and sleet over the nighttime hours some places may pick up a tenth of an inch of sleet and ice which will create dangerous driving conditions. The region highlighted in light blue is our snow  band that will develop with this low as it moves towards the Northeast places like Northeast Arkansas could again see 1-2in of snowfall while places in Kentucky and West Virginia could be dealing with 4-6in of snowfall from this storm.

Looking at the potential impacts of this storm for certain cities and how they will be impacted. (These conditions are for Dec 29 and 30).

Baltimore, MD: (The 29th will start out quite but rapidly intensify as the chance of snow moves into the region accumulations of 1-3in is very possible for the Metro area west of the bay.

Storm Summary: This storm system is moving right along the same path as the Christmas storm did so many places are seeing the same kind of weather they saw just about three days ago. We have the heavy snow band setting up in Arkansas towards the Northeast again and also heavy rains across Louisiana and Mississippi which will eventually push into the Alabama and Georgia areas. This time the storm system will not have as big of a severe weather outbreak with it as the dynamics are just lacking this time unlike the Christmas storm. There will still be some places that see more ice accumulations this time which will make driving dangerous through those regions and this storm looks like it will have another good punch moving up the Northeast through the weekend brining some heavier snows to the region along with more ice and freezing rain as well. This storm system is also moving fairly fast and should clear the United States by Sunday Night with just a few light snow showers left over the Northeast in the Boston and Maine regions.
