Because that's what the weather is doing! 4 degrees tonight, 50 degrees a week from today, 60 degrees next Thursday and 5 degrees next Sunday. Yeah!
From the National Weather Service:
.Short Term...(Today through Wednesday) Issued at 238 AM EST Tue Jan 25 2022 ...DANGEROUS WIND CHILLS TONIGHT AND EARLY TOMORROW... Today and Tonight. There have been a few flurries across central Indiana during the overnight hours, but as clouds continue to scatter through daybreak, expect that these should quickly come to an end. In the aftermath of the cold front, strong CAA both at the surface and aloft will help to bring the coldest air of the season so far to much of central Indiana. Daytime highs today across Minnesota and southern Wisconsin will be well below zero with surface winds advecting that air into the area through the overnight hours. Across central Indiana, highs will vary significantly from the north to the south with lows near 20 in the south while only 10 in the north. That colder air from the northwest will continue to push into central Indiana during the overnight hours and combined with mostly clear skies will allow for temperatures to drop to near 0 for much of the area with sub-zero temperatures across the northern counties. Temperatures aloft will run even colder, so with no near surface inversion, winds should remain gusty through the night into the early daytime hours tomorrow which will allow for wind chills to drop to near -20 across north central Indiana with increasing values further south where the temperatures will remain higher. With all this in mind, have elected to go with a Wind Chill Advisory across those northern counties. Wednesday. Cool conditions then continue into Wednesday with a slow temperature recovery with the continued CAA counteracting the diurnal radiational warming. Do think that temps should rise to the 15-20 degree mark for most due to a gradual wind shift during the daytime hours to be more southerly by mid afternoon. Wind speeds will be relatively minimal with a developing surface high across the area, but with the loss of the CAA, radiational warming should win out for the day. && .Long Term...(Wednesday night through Monday) Issued at 238 AM EST Tue Jan 25 2022 A highly amplified pattern aloft will persist into the weekend... anchored by a ridge over the eastern Pacific Ocean and West Coast and a broad trough over much of the country east of the Rockies. This will maintain a cold and largely dry pattern for the rest of the week into the weekend with Arctic air across the region. The only threat for any precipitation in the extended comes Thursday and Thursday night as a weakening wave aloft tracks into the Tennessee Valley and interacts with a cold front dropping out of the upper Midwest. While the system will be lacking moisture initially...the interaction of the features will generate lift with the potential for areas of light snow to develop and impact the area Thursday afternoon and night. At this point...light accumulations under an inch would be possible in spots. Once the front passes...a renewed surge of very cold air will advect into the region with the combination of cold advection and lingering stratus in the cyclonic flow behind the boundary potentially supporting a period for flurries to linger into Friday before high pressure takes over. Another strong area of high pressure will expand into the Ohio Valley and Great Lakes for the weekend with cold and dry conditions. Highs Friday and Saturday will only make it into the 20s with teens for overnight lows. Upper level flow will recover by late weekend into early next week in response to a portion of the western ridge kicking east into the central Plains. Highs will respond in kind...warming back into the 40s over much of the forecast area by next Tuesday.
