As of January 21, January 2021 is the 15th warmest (mean temperature) since 1879 in Greater Lafayette (Purdue University 1879-1943...Purdue Airport 1944-Present).
Highs today were mild at 43-51 with peak winds gusts as high as 42 mph.
Colder weather is ahead.
Winter precipitation is ahead as well............let's focus on Sunday, Monday, Tuesday & Thursday...........& then systems in early February....
Snow to ice to rain to ice to snow is likely in the late Sunday to early Tuesday time frame.
The exact time line of change-overs continues to be unclear, but minor snow/ice accumulation is possible early in the system & again late.
The middle may have rain........however, the north looks to be the last to change to rain, so areas along & north of US 24 will have a much longer duration of frozen precipitation.
If it tracks a bit more to the south, then there will less to no rain & more frozen precipitation.
This is an all-snow system, but the track is unclear. This will dictate any snowfall amounts.
There is a system, but close monitoring over the next several days will determine magnitude of impacts here.
I am focused on a mantle of snow & a clear calm night with strong surface high by end of next week meaning lows near 0.
A quickly as the cold snap settles in, it moves out rapidly. Strong southerly winds with much warmer weather & rainfall should arrive by February 1.
This is the first of many systems to February 10 with surges of above to well-above normal temperatures.
This also means multiple rounds of severe weather across the southern U.S. to parts of the Ohio Valley & perhaps even as far north as our area.
February 5-6 time period shows strong storm system with near/record warmth & severe weather risk here. We will monitor.
Much colder weather with ice & then snow are likely in mid-February.
Burst of much warmer, wetter weather looks likely in late February.
