Our arctic blast
is pretty much on schedule & going according the First Alert Forecast. The map below is Tue. morning's lows courtesy our Jax N.W.S.
: (JIA missed the record low (21) for the day by just 1 degree & should easily break the record low max for Tue. of 45 in 1970 (forecast is 39):
Original Mon. evening post:
The cold wave has arrived....
The arctic blast that’s been well advertised arrived Mon. & will peak 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:
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. Winds will become more onshore after midnight which will moderate temps. some closer to the intracoastal & the beaches but will still likely dip below 32 -- at least for a few hours.
Temps. will be below freezing:
** approx. 10-15 hours inland through late Tue. morning....then another 16+ hours inland 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 wipe out at least some of the insects & pollen. In addition, the cold air 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 into the weekend.
There will be, however, plenty of clouds & some rain accompanying the milder air. First...a few coastal showers will occur Thu.-Fri. Then an approaching cold front will trigger widespread showers over at least parts of the weekend.

"PG Miller" offers these cold tips:
Those that are particularly sensitive to cold (older residents and infants) need special attention to stay protected. Check on them on a regular basis. The safest way to deal with the extreme cold is to remain inside. If you need to venture outdoors, it is critical to protect your extremities (head, hands and feet). Ski hats, gloves, boots and heavy socks are in order. Dress in layers in order to trap heat around your body core. Minimize your time outdoors to only that necessary.
Pets can suffer the same hypothermia issues as people. Bring pets indoors and minimize their time outdoors.
Florida homes are not built nor designed to cope with extended cold weather situations. The safest way to protect your water pipes is to properly insulate exposed pipes. When a freeze is impending, suggest “cracking” your outdoor water spigots to drip every 15 seconds. You might consider also opening the furthest located (from where the water service enters the house) faucet inside the house to keep the water moving and preventing a freeze. While you will waste some water, it will be significantly less than the cost of repairing frozen/broken pipes as well as avoiding the inconvenience. If your kitchen/bathroom sinks are on exterior walls, open the cabinet doors to let air circulate around your pipes.
If possible, move plants indoors or into the garage. Exterior sensitive plants can be covered with canvas drop cloths or specially designed “freeze Plankets”. These covers should be lifted as soon as temperatures rise above freezing or the plants could overheat and sweat.
Automobiles are also affected by extreme cold weather. Do not “hard start” your car. Start the engine, let the radiator warm the engine block and engine oil to operating temperatures before driving off. Defrost your windshield fully; do not drive off with “peep holes” as this is totally unsafe. Never activate the windshield washer as this may freeze your windshield or even crack the glass as the water hits the frozen windshield. Ensure your wipers are free to move and not frozen to the windshield before turning them on. If your car battery was borderline, it will expire in cold weather. Also ensure your tires are up to required air pressure levels before the cold as the freeze will cause a drop in tire pressure.
If your heat pump will not operate in cold weather, most likely the culprit is your condenser capacitor. If it has to be replaced, request a “dual voltage unit”.
"Rain-X" offers these driving tips:
1. Use a high quality glass cleaner and window treatment to improve wet weather driving visibility on your windshield and glass.
2. Change your wiper blades every 6-12 months so that they make proper contact with the windshield surface. Old blades can begin to squeak, chatter, skip, smear or streak reducing driving visibility.
3. Use a superior windshield wiper fluid and/or de-icer fluid with a streak-free formula for advanced cleaning power. The blue low quality wiper fluid can cause wiper blades to crack or break and does not protect against streaking.
4. Apply an anti-fog glass treatment to avoid unwanted fog that might appear on the exterior and interior of your car to avoid impair visibility.
