A cold wave is on the way!

The arctic blast that’s been well advertised is on the move & arrives through the day Mon. peaking for the First Coast Mon. night through Wed. morning. Depending on how one measures it, this is the coldest air in at least 3 years (at night) & in 10 years (by day). The First Alert Forecast:

TODAY (MON.): The day begins unseasonably warm with temps. in the 60s, possibly near 70s for a short time this morning!  The cold front -- accompanied by a band of showers -- will reach Lake City & Waycross by 8am... Jax by 10am or so... & St. Augustine & Palatka by at least noon.  Slowly falling temps. will follow through the afternoon despite clearing skies. Winds will become gusty from the north/northwest at 15-30 mph.  The coldest air lags the cold front so temps. will only slowly fall through the 50s reaching the 40s by late afternoon but winds will make it feel colder.

Temps. plunging to near 20 degrees by morning with wind chills of zero to 10 above. The record for the date at JIA is 21 set in 1924.

TUESDAY: A brutally cold day for this area with a high of only 39 - the record low high for JIA is 45 set in 1970.  Winds will slowly decrease but wind chills will stay below freezing virtually all day.

TUESDAY NIGHT: Clear, cold with lows near the daily record of 21 set in 1970.

Temps. will be below freezing:

** approx. 12 hours from midnight Mon. to noon Tue....then another 16 hours from 6pm Tue. to 10am Wed. Such extended cold could be a problem for older homes with pipes exposed. Remember to cover outdoor faucets & bring hoses inside. And be extremely careful with alternative heat sources such as fireplaces and especially space heaters.

And remember to check on your neighbors, the elderly & pets. Most plants that cannot withstand extreme cold will either perish or at least become dormant.

The good news is that the cold will not be here for long with temps. staying above freezing for the rest of the week into the weekend once we’re above 32 Wed. morning. In fact, 70+ degrees can be expected by late week.
