February 3, 1:45 PM Weather Forecast Update

Colder weather with icy mix & snow ahead.

Temperatures are 48-57 northwest to southeast over the viewing area as of 1 p.m. with lots of clouds.  This, after lows of 28-35 this morning with some fog with wind turn to east & northeast for a bit as front moved southward overnight.

Highs should reach 54-65 from north to south today with around 60 for Greater Lafayette.

With the front a bit more north now, the southern 2/3 of the area is quite mild, but this front will be on the move back southward tonight, bringing cooler air with wind turn to northeast.

Also, a secondary cold front will slide southward & bring enough cold air for icy precipitation by tomorrow.

ROUND #1:  SHOWERS

So, showers develop & increase tonight with winds picking up from the northeast behind both fronts.  Isolated thunder is possible.

Lows of 34-50 are likely from northwest to southeast by 7 a.m. Tuesday morning.

Temperatures should fall to 27-33 from northwest to southeast by Tuesday afternoon with any rain lulling to drizzle, then potential of some freezing drizzle.

ROUND #2:  SNOW & SLEET WITH SOME FREEZING RAIN

Late Tuesday afternoon-night, a round of snow, sleet (with some freezing rain south) is likely.

By early Wednesday morning, up to 0.1" sleet & freezing rain is possible & 1" or less of snowfall.  HOWEVER, there will likely be a narrow zone of 1-2.5" of snow, but it is a bit unclear as to where that band will set up.

Current analysis suggests that band will run Rainsville to Greater Lafayette to Galveston to Grissom ARB.  HOWEVER, it is still a bit unclear & that may shift, so stay tuned!

Winds look to become strong from the northeast at up to 35 mph.

ROUND #3:  SNOW, SLEET & SOME FREEZING RAIN

Snow, sleet & some freezing rain are possible Wednesday afternoon-night with temperatures 23-30.  At this point, it appears that the southern & southeastern areas have a better potential of this being mainly icing with northwestern areas have a better potential of all snow.

In the central part of the viewing area, it is both.

Accumulations are likely from snow & ice, but amounts are still a bit unclear.

There is some data suggesting 3-6" from Greater Lafayette & northwestward & all ice & now snow with a VERY SHARP cut-off southwest of that line. 

A band of 6-9" is possible with this round, but will likley occur northwest of our viewing area.

That sharp line between 3-6" snow & just 0.5" crusty sleet & freezing rain may run Veedersburg to Romney to Burlington to Grissom ARB.

Strong, gusty northeast to north, then northwest winds up to 40 mph will blow any snow around Wednesday-Thursday morning.

We will drop from 56-64 Sunday to lows potentially single digits to teens by Thursday night.

A gusty clipper comes through Friday or Saturday with snow showers & some very minor accumulation, followed by some very cold rain developing Sunday (which may begin as freezing rain far north) as highs warm from the 20s & 30s to 36-41.

Rain is likely Sunday night with fog, but freezing rain may occur in the north, while this same storm system dumps heavy snowfall over Iowa & Wisconsin to perhaps as far south as northwestern Illinois.

A couple rounds of mixed wintry precipitation & just snow in the February 10-13 time frame.

Temperatures will average below normal, but nothing screams -20 brutal cold up to February 18 just yet.  That is locked up from Minnesota to Nebraska, then northwestward to the Dakotas, Montana & then bleeding into the Pacific Northwest.  Temperatures may drop up to 40 degrees below normal.

We will monitor!
