Our warming trend is beginning but Fri. highs will still be below avg. topping out in the mid 60s. Highs Sat. will be near 70.... near 75 Sunday -- but cooler at the beaches, especially Sat. -- & all the way to near 80 degrees Mon. No significant rain through Mon. & showers with a cold front Mon. night/early Tue. look to be light. So a chance to dry out.
Saturday -- March 1st -- is the beginning of "meteorological spring". In weather circles, spring is considered to be March, April & May vs. the vernal equinox. For Jax, avg. temps. warm from 71 degrees March 1st to 77 April 1st to 82 degrees May 1st.
Our El Nino Southern Oscillation (ENSO) has been neutral -- neither significantly persistently warm & or cold -- for a number of months in a row. But long range global forecast models are indicating the possibility of at least a weak El Nino developing late in the spring &/or summer. The image below is the forecast from various models.... the 2nd image is the area -- near the equator in the Pacific -- where an El Nino will occur (there has been some cooling during the past couple of months). If an El Nino does develop, a hurricane season with a lower number of storms will be possible but would be highly dependent on the intensity & duration of the El Nino.

A NOAA satellite was launched from Japan Thu. -- click ** here **. Some info:
1.US and Japan are partners: GPM: Global Precipitation - the size of a small fire-truck circle earth every 90 minutes.
2.instruments will take “cat-scans” of storms from 250 miles above the earth
3. For the first time from space a “dual- Radar” will be able to measure snowfall.
Rainfall measurements every 3 hours will help forecasters issue warnings for flooding, such as the record Sept 2013 Colorado flood, over 10 inches of rain.
It's possible that sharks could help predict the intensity of tropical storms & hurricanes. Though the story just ran on CBS Wed. -- click ** here **, there have been indications of such going back at least 10 years. It seems that sharks are sensitive to water temp. changes & especially pressure change.
