FLORIDA WINTER RAINS ARE TYPICAL OF AN EL NINO

2014-03-28_165812

JACKSONVILLE AREA RAINFALL TOTAL TO BE ABOUT ONE INCH ON SATURDAY.

The Climate Prediction Center reports that we are in the neutral phase of El Nino/La Nina, but our colder and wetter than average winter is what frequently occurs in an El Nino winter. The CPC says there’s a 50% chance of an El Nino developing by late summer. If that occurs, the hurricane season may have fewer storms than recent years.

Jacksonville’s rainfall since January 1 has been 13.54 inches with another inch predicted between Thursday and Sunday morning. The storm track most of this winter has been over the Gulf states and up the Atlantic seaboard, with a secondary track from the Midwest and Great Lakes region into eastern Canada. Incredible winter snowfall totals  have made 2014 a difficult winter for many of our neighbors to the north!

The first map could be viewed at the issue of a Hurricane Watch. It is subject to be changed every 6 hours with the next full NHC advisory package. Due to processing time, it may not be available until about 45 to 60 minutes following the advisory release.

THE TROPICAL WEATHER OUTLOOK AND TROPICAL CYCLONE DISCUSSION WILL BE IN MIXED CASE, NOT ALL CAPS.

SPRING IS FINALLY HERE!

No, this isn’t a Green-eyed Monster. It’s a look at the sun by NOAA’s Space Weather Prediction Center and Prediction Testbed. The sun was located directly over the Earth’s equator at 12:57 PM EDT today (Thursday March 20). This was the occurrence of our Vernal Equinox. Data from this image is used to determine Solar flares that can affect communication and create the Aurora over the earth’s Polar regions.

THE WORST OF WINTER IS BEHIND US!

Arctic Oscillation

In December 2013, Jacksonville had 8 days of 80 degrees or higher when the Arctic Oscillations were on the “warm” side. That month’s temperatures averaged nearly 5 degrees above the norm. The first Arctic to reach north Florida was on January 6 when a hard freeze sent temperatures into the low 20s and upper teens. Jacksonville had 8 freezes from January intrusions of the Polar Vortex that caused the month to average nearly 4 degrees colder than normal. The city had only one freezing day in February and none so far in March as the only effect of last week’s Arctic outbreak was only two cold overcast days that failed to climb above of the 40s.

The remainder of this month appears to be free of freezing temps in the Jacksonville area, but outlying places in southeast Georgia and the Suwannee Valley may have a few more freezing mornings between now and April 5.

THE END OF ARCTIC OUTBREAKS?

Jacksonville escaped a brief freeze with a low of 33 on February 28. The eastern U.S. is still under the grip of the early March Arctic chill while it now appears likely that northeast Florida may only have one or two mornings in the upper 30s around March 14, but no freezes. We should be having a good season for spring planting beginning with March 15.

WATCHING MARCH COLD SNAPS FOR SPRING PLANT PROTECTION

This is the time to plant tomatoes in North Florida in order to have a bountiful harvest before summer heat reduces the yield in June. The main concern is the risk of a sudden freeze in March.  But it’s worth the risk because it is easy to shelter the plants with boxes or buckets should an overnight freeze occur.

The worst of winter is behind us. While January had 8 freezes and only 6 days reaching 70 degrees or higher, February has had only one freeze and 13 days reaching 70 degrees or higher. NOAA’s Climate Prediction Center indicates that the 90-day period March through May should be warmer than normal. That should be good news for North Florida and Southeast Georgia gardeners!

FLORIDA ONLY STATE WITHOUT SNOW!

Snow States

The National Oceanic and Atmospheric Administration (NOAA) released this map showing snow touching every state, except Florida. Not shown, Alaska and Hawaii also had snow. The wicked ice and snow storms paralyzed cities as close as Atlanta, while we mainly got the bitter cold delivered by the Polar Jet Stream. I hope you enjoy this ride with weather changes as we wind up February.
