Aviation. Dry and VFR conditions throughout the period. Northwest winds breezy and gusty at times this afternoon and evening. Wind relaxes some overnight before increasing once again tomorrow morning.

Update . Cooler and drier air continues to filter down the Florida peninsula. Northwesterly winds will at times be breezy and gusty. No major changes to the current forecast with a cool and dry day across South Florida.

Discussion .

Short Term (Today-Saturday night):

Models and sfc analyses depict broad high pressure across the region, with a mid level ridge gradually migrating from the east CONUS to the west Atlantic during the weekend. This synoptic setup will keep prevailing NW/NNW winds across the Florida peninsula through the short term, with continuing cold and dry air advection, along with benign weather conditions prevailing over SoFlo.

Expect temperatures to remain well below normals today with afternoon highs struggling to surpass the upper 60s across much of SoFlo. Nighttime lows will likely see areas over the northern interior dropping into the upper 30s, while coastal areas will remain in the upper 40s to low 50s.

For Saturday afternoon, expect a similar temperature profile but a few degrees warmer, especially over the northern and interior areas.

All in all, generally cool and dry weather will prevail with very benign weather conditions across SoFlo through Saturday night. Enjoy!

Long term (Sunday-Thursday):

The long term begins with an east coast trough beginning to slide eastward allowing for a more progressive zonal flow to set up across the region. This will be the start of a warming trends as surface high pressure begins to also slide eastward across the western north Atlantic by early next week. With the surface flow returning to a more southeasterly direction, moisture will gradually increase with time. With the increase in low level moisture, cannot rule out a stray shower or two by on Tuesday, especially across the marine zones where the best boundary layer moisture manifests.

Going into midweek, another pattern change begins to evolve. An eastern Pacific trough will slide southward into the Desert Southwest early next week. From this point on there are notable difference among the GFS and ECM. The GFS tends to keep the wave open, where the ECM closes off this feature across northwest Mexico. By closing the upper level wave, the ECM has come in a bit slower with the progression downstream toward our area compared to earlier runs. The temporal issues with the eventual frontal passage will limit POPs for the time being until a better handle on timing shakes out. That said, another frontal passage looks like a safe bet late in the week. If models are correct and the front does make it down to our region, don't think temperatures will be as cool behind this front given its Pacific origin, unless of course the front phases with another trough that might have Canadian/continental roots.

Marine .

NNW winds are expected to drop to below advisory levels today at all coastal waters, but some SCEC periods are expected. A reinforcing shot of cold air will again bring increasing northwesterly winds through the rest of the weekend, with winds and seas near or at SCA thresholds once again. By early next week, broad high pressure will expand across the region and relaxing pressure gradients, which in turn will reduce wind speeds. Then by midweek, an approaching cold front may bring an increase in wind speeds to near advisory levels.

Beach Forecast .

A moderate risk of rip currents will continue for all South Florida beaches today with robust NW winds, and in the case of the Atlantic coast, a residual swell. There still may be an elevated risk of rip currents going into Saturday and Sunday, especially for the Gulf beaches. Beyond the weekend, the rip current risk will decrease for the Gulf and increase early next week for the entire east coast as flow turns more out of the east.

Fire Weather .

Relative humidity values are likely to drop below critical thresholds this afternoon and Saturday afternoon across the region with multiple hours below 35 percent possible. The low RH values may help with the ease of igniting/spread of fire. However, there is low confidence on meeting red flag criteria due to 20 ft winds below threshold and borderline and/or below thresholds fuel conditions/ERC values. That said, today and tomorrow afternoons will represent periods of enhanced fire weather danger.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
