|Colorized Depiction with labels of surface temperature in Fahrenheit Degrees at 730AM EST. The 60F line HAD been north of Dead Central prior to the front early, early this morning. Blue arrows show direction of colder air impingement southward.|
TODAY: Best surprise is no surprise in the case of today. That being, the cold front went through per schedule and is now toward the south end of Lake Okeechobee one hour after sunrise. Much drier air is located over North Florida with dew point temperatures in the upper teens to mid 20Fs. In comparison, the Daytona Area has dewpoints now in the mid-upper 30Fs and East Central toward Canaveral remains a good 10-15 degrees higher. The dew points are a good determinant of how dry the air is. The lower the dewpoint the drier the air. The dry air is working south all day along with the colder air (drier air holds less heat).
Highs today will likely not get above 60F north of a line running through Melbourne or Palm Bay area toward South Tampa Bay...with highs near the lower 70Fs far South Florida. Highs in the lower 50Fs North Florida. NW wind all day at 10-15mph. This cold spell in a sense will not be as bad as the previous one for two reasons.
1) It looks like we will start out with less brisk of a wind thus wind chill temperatures not a big player; and,
2) All in all over night lows not looking to get toward freezing on any overnight period.
This will simply be a bit of a prolonged very cool to cold period with intermittent cloudier periods, especially over the Southern 1/2 to 1/3 of the state through the weekend. Thus, although it might be cooler further north (North Central and North), this area is more likely to see more of the sun and feel direct warmth from it's rays as opposed to those in South Florida. Give or take which ever one prefers.
SATURDAY/SUNDAY: Coldest overall day, colder than today all areas by generally 3-6 degrees during the day and much colder Saturday morning all areas, as well as Sunday morning. The warmest overnight lows will likely be EAST of the both rivers in Brevard County and southward. Same reasoning will apply far west coast south of Tampa. Lows do not appear will get to freezing except toward far North Florida, but mid-upper 30Fs and lower 40Fs could be widespread these mornings. Those warmer areas will likely remain closer to the mid-upper 40Fs, and warmer Keys and coastal SE Florida.
MONDAY: Still no change in previous line of thinking. Warmer east coast as onshore winds develop over night Sunday night or late in the day, preventing temperatures from falling along the east coast. No truly Cold spell for QUITE SOME TIME TO COME also remains at this point; only perioeds "on the cool side" from time to time (so far). Maybe some showers or at least a cloudy period toward Wednesday with the next front, but as stated, cold air with this next boundary has yet to materialize more than a few tics below normal seasonable readings.
