National Weather Summary for Thursday, March 9, 2017

by David Moran, on Mar 9, 2017 11:04:54 AM

Thunderstorms may develop across portions of the Ozarks and Tennessee Valley on Thursday ahead of a cold front. Across portions of the Northeast, snow is expected to develop late Thursday into Friday as an area of low pressure tracks to the south of the region. A stalled frontal boundary over the Northern Plains will be the focus for the development of snow through noon Saturday. Dense fog is expected along the Texas coast through early Friday.

US Hazards for Thursday, March 9, 2017US Hazards

Region 1
A weak area of low pressure will move eastward along a southward-moving cold front across Kansas and Missouri throughout the day. In addition, a dryline will extend southward into central Oklahoma before it is overtaken by the advancing cold front late in the afternoon and evening. A couple of isolated severe thunderstorms capable of producing large hail and damaging winds may develop across southeastern Kansas as early as late this morning. Any activity that develops would shift into central and southern Missouri by early to mid afternoon. Storm coverage is forecast to increase during the mid to late afternoon with additional scattered thunderstorms expected across southern Missouri. A squall line may build into portions of eastern and central Oklahoma, posing a risk for large hail and damaging winds. An isolated tornado cannot be ruled out. During the evening, storms will congeal into a squall line that will surge southward across portions of Arkansas and Tennessee. Damaging winds along the leading edge of the line will be the primary hazard. Storms may move into northern portions of Mississippi and Alabama overnight.

Update 11:20am CST: Severe Thunderstorm Watch in effect for portions of southeastern Kansas and southwestern Missouri until 7pm CST.

Winds gusting in excess of 25 mph will reduce visibilities to less than 2 miles. Wind chills between -5 and -10 are also expected. Snow will spread into the Plains late Friday and continue through noon Saturday.

Significant Snowfall Possible for the Midwest and Tennessee River Valley on Saturday

Significant Snowfall Risk Outline for Saturday, March 11, 2017Significant Snowfall Risk Outline for Saturday

A Look Ahead
Into Tuesday and Wednesday, there will be the potential for a late winter Nor'Easter Tuesday into Wednesday. Model guidance is starting to come into agreement on this potential. Latest indications show that a large upper level trough will move into the eastern US on Tuesday, with a surface low to deepen off the Atlantic coast while tracking northeast. Cold air will likely be in place across the region, therefore, significant winter weather will largely depend on placement and strength of the aforementioned low. If this low tracks along the coast, several inches of snow and strong winds will be possible across a large portion of the Northeast Tuesday into Wednesday.
