Another night, another Wind Chill Advisory. Tonight’s Advisory will last through 11:00 A.M. ET. Between now and then, wind chill values may dip as low as -30° at times! Frostbite and hypothermia may begin to occur in as little as 20 minutes in conditions such as tonight’s, so be safe.
While warmer weather is expected to finally return to Greater Lafayette during the next five or six days, don’t anticipate a mild Saturday ahead for us; most of us won’t even see afternoon highs climb out of the single digits. We’ll only peak at 8° in Lafayette tomorrow.
After one last night of sub-zero temperatures (for the foreseeable future), the mercury will surpass a threshold not seen here in Lafayette in virtually two weeks! Current data suggests that as of 11:00 A.M. ET on Sunday, the temperature in Lafayette will reach 20°. The last time we saw that temperature was on Christmas morning at 3:00 A.M. ET.
The longest streak of sub-twenty degree temperatures in Lafayette I could find in the available National Weather Service data was 10 days. Now at 12 days and counting, it appears as though we’ll at least close in on the two week mark. The latest models indicate that we’ll go 13 days and 8 hours straight without reaching 20°!
While the warmup in store for us all will be well deserved after the brutally cold conditions we’ve had to deal with these last 12 days, the snow and possible ice expected as a result wasn’t exactly what we all asked for.
Gulf moisture migrating northward will interact with an arctic air mass flowing in from the Great Plains. It’s possible that we may receive a prolonged period of freezing rain or sleet beginning Sunday afternoon, though were still a bit too far out to set any timeline in stone. Other models indicate that the Sunday into Monday system will be primarily snowfall. We’ll know more tomorrow.
As for now, I’m anticipating a brief period of snow beginning after our lunch hour on Sunday followed by periodic sleet and freezing rainfall. That evening, temperatures will be low enough both at the surface and aloft to support only snowfall. The last of the precipitation should exit after dawn on Monday.
Though our commute Monday may be a slick one, at least temperatures finally climb back into the 30s, 40s and possible even 50s by the end of the next work week. As long as it holds, that high of 54° next Thursday’s going to feel like summer! Have a great weekend!
