Will Be Able to Make More Detailed Snowfall Map Shortly (Rather Than a 3-6″ Map)January 24th, 2013 at 11:55 am by Chad Evans under Chad's WLFI Weather Blog
LATE THURSDAY NIGHT-FRIDAY…………
Looks like I am going to be able to take the broad 3-6″ forecast & dissect it & line up some 1″ or 2″ increments with a new map shortly.
I am currently looking at the speed of the system to see if I need to cut or increase totals. I am also looking at where the greatest vertical velocities will be located for snow crystal production.
Frontagenic forcing underneath +115 mph upper jet looks good, especially in the northeastern 1/2 of the area with baroclinically-induced low-level jet nosing in late tonight into southern Indiana.
Meanwhile a damaging ice storm with up to 0.75″ of ice is likely from eastern Tennessee to North Carolina, Virginia & northeast Georgia in the Appalachians & Piedmont. This will occur in a broad swath of icing from the coast of North Carolina to Oklahoma to as far north as far southern Indiana & as far south as Huntsville, Alabama.
NEXT WINTRY WEATHER ISSUE: SUNDAY P.M.-SUNDAY EVENING…………..
Next wintry issue will arise Sunday afternoon (it is speeding up) with a mix of freezing rain, sleet & snow possible with minor accumulations. The mix will change to all rain from southwest to northeast Sunday night as temperatures rise.
RAIN & BRIEFLY MUCH WARMER………………..
Periodic rain & drizzle is likely Monday with potential break Monday night. Another round of rain is likely Tuesday with warm highs in the 50s.
Rain looks to exit Tuesday night.
COLDER WITH SNOWFALL NEARBY MID- TO LATE-NEXT WEEK (NEED TO WATCH)………..
Colder air will move in Wednesday with dry weather.
We’ll need to watch Wednesday night-Thursday. There are signs of a storm system riding the front northeastward. Indications points towards a band of accumulating snowfall from Missouri to Ohio. It is too early to try to pinpoint how much of an effect this system will have on our viewing area.
