Quick Early Tuesday Morning Update:
“BLIZZARD WARNING” for SW & SC Louisiana? Who would have expected to see that word used across the Cajun Prairie?
Don’t be fooled by periodic breaks in the snowfall this morning. However, the latest NWS projections suggest that snow totals in SW Louisiana may end up a bit below the widespread 4″+ expected there. So far, the NWS is not lowering the numbers for areas east of the Atchafalaya Basin. Also, note that the numbers have decreased for much of Central LA.
The attached HRRR is somewhat overdoing the northward extent of snowfall. However, focus on the timing of the west-to-east ending of the activity. With luck, Lafayette and Baton Rouge metro areas may see an end to the snow around mid-afternoon. Public works may have some daylight to assess/evaluate conditions as they plan to attack roads. It could even end by/before 6-7 PM for metro New Orleans.
Remember, it gets much colder tonight than last night. In the end, I still think that the cold will be the biggest problem with this storm, although the snow will get the attention (for now).
