All eyes on a strong cold front that will roll south the next couple days. The air following this front will easily be the coldest of the season so far BUT the chill we be fleeting. The front has brought snow across much of the midwest... the first accumulating snow of the season for parts of the Ohio Valley, mid Atlantic & Northeast and will bring flurries & snow showers as far south as the higher elevations of Ga. & the Carolina's.

The front should be late enough to allow for another seasonably mild day Tue. for the First Coast with highs in the upper 60s to mid 70s. North/northeast winds should pick up enough by late afternoon to drop temps. a few degrees. But the much colder air moves in Tue. night as temps. dip into the 40s then only recover to the 50s Wed. with north/northeast winds of 15-25 & higher gusts.

Temp. map below courtesy Unisys:

Temps. Wed. night - early Thu. will dip into the 30s west & northwest of Jax... near 40 on the N & W side of Jax to about I-95.... 40s to around 50 across the middle of Duval Co. to the 50s along the intracoastal & beaches where onshore winds will greatly modify the air mass. Winds will stay up some which means low wind chills but the "mixing" will also keep temps. from dropping as low as they might otherwise.

Despite the strong push of chilly air, it will have no staying power. Temps. begin to moderate Thu.... hitting the mid to upper 60s in the afternoon which is still below the avg. of 74-75 degrees with a breezy onshore east wind. But winds become more southeast Fri. through the weekend drawing much milder air northward sending First Coast temps. back into the 70s Fri. through the weekend with lows that will moderate into the 50s & even 60s given higher humidity.

As for rain....the strong cold front will move through the area mainly dry though the onshore flow will help bring some drizzle & light rain -- mainly from I-95 to the coast late Tue. night into Wed. Most inland areas -- west of I-95 -- will not have measurable rain & amounts closer to the coast will be less than a quarter of an inch.

There will be a much better chance for rain over the weekend into early next week as the high humidity will combine with upper level disturbances within a broad upper level southwest flow & -- eventually -- an approaching cool front which will likely produce several rounds of rain.

A salute to all our veterans on a day that was perfect at our local beaches as the pic below illustrates.
