Near Term [Through Tonight]...
High Pressure Will Build Into The Region Tonight Resulting In Near Calm Winds. With The Clear Skies And Dry Conditions, Expect Temperatures To Drop Quickly Tonight.
While Some Of The Guidance Has Trended Colder This Cycle, It Doesn`t Appear As Though It Will Get Cold Enough To Support A Hard Freeze Warning, Though There Is A Possibility A Few Spots In The Southeast Florida Big Bend Approaching The Mid 20s.
However, A Light Freeze Inland Looks Like A Sure Bet.
Short Term [Monday Through Tuesday Night]...
After A Rather Cold Start Across The Region With A Light Freeze Expected Overnight, Afternoon Temperatures Should Finally Moderate Back Up Into The Middle 60s Across Most Areas On Monday Afternoon Under Plenty Of Sunshine.
Monday Night Should Be Quite A Bit Milder As Well As Surface Winds Begin To Veer Around To The South.
Low Temps Are Expected To Range From The Mid To Upper 30s In A Small Area Near The Suwannee Valley To The Upper 40s To Lower 50s To The West Of The Apalachicola River.
On Tuesday And Tuesday Night, The Next (And Last For Quite Some Time) Low Pressure System And Associated Cold Front Will Approach The Region From The West And Swing Rapidly Through The Cwa Overnight Tuesday Night.
While Scattered Showers And Isolated Thunderstorms Are Expected With This System, We Are Only Anticipating A Low Qpf Event (With Storm Total Precip Between .05" And .15").
This Additional Rainfall Will Have Almost No Impact On Our Ongoing River Flooding.
Also, It Should Be Noted That High Temps Will Finally Break Back Into The Lower To Middle 70s Before Any Showers Or Storms Reach The Area.
Long Term [Wednesday Through Sunday]...
After The Next Low Pressure System And Associated Cold Front
Sweep Through Our Cwa On Tuesday Night, A Very Benign Synoptic
Pattern Appears In Store For The Region Throughout The Extended
Since This Initial Cold Front Does Not Appear To Be A Significant Qpf Producer (Due To Lack Of Return Flow Moisture And Its Very Progressive Movement), And With No Additional Rainfall Expected After This System Through The Upcoming Weekend, Conditions Will Be Ideal For Our Area Rivers, Many Which Are Still In Flood Stage, To Continue To Subside.
As For Temperatures, We Do Expect A Shot Of Cooler And Drier Air Behind The Front From Wed-Fri (Though Not Nearly As Cold As This Last Air Mass), With Conditions Returning To Back Towards Or Even A Bit Milder Than Climatology For Next Weekend.
Aviation [Through 18z Monday]...
Vfr Conditions Will Prevail Throughout The Period.
With The Northwesterly Winds A Bit Slower To Subside Over The Offshore Legs, Will Continue The Cautionary Headline Into This
Winds And Seas Will Continue To Diminish Over The Marine Area During The Overnight And Morning Hours On Monday, As The Wind
Direction Gradually Swings Around From Offshore To Onshore By Monday Afternoon.
Then, Winds And Seas Will Begin To Approach Cautionary Levels Once Again On Monday Night And Tuesday, As The Next Cold Front Approaches The Coastal Waters From The West.
Behind This Cold Front, A Strong Small Craft Advisory Is Expected Tuesday Night Into Wednesday Night With Gusty Northwesterly Winds.
Dry Conditions Are Expected Tomorrow, But Ercs And Wind Speeds Will Be Too Low For Red Flag Warnings.
A Chance Of Rain Is Back In The Forecast For Tuesday With Drier Conditions Returning During Wednesday.
Slow Improvement Continues To Be Noted Along Many Of The Rivers In Our Area, Although Many Of The Lower Portions Of The Rivers (NEAR THE GULF OF Mexico) Are Still In Flood Stage.
Flows Are On The Decrease On The Chipola, Ochlockonee, Choctawhatchee, And Flint Rivers.
The Withlacoochee At Pinetta Is In The Process Of Cresting, Though
It Will Likely Remain At Or Near Its Crest Height Of 84.3 Feet For
The Next 18 To 24 Hours Before Beginning A Slow Decrease. There
Still Is A Lot Of Water To Drain Down The Withlacoochee Toward The
Suwannee River, So Flooding Along The Eastern Portion Of Madison
County, Particularly South Of The Pinetta Gage, Will Be Slow To
The Primary Focus For River Flooding Will Shift To The Suwannee
River By Tuesday. Unusually High Inflows From The Withlacoochee And Alapaha Rivers Will Help Drive The Suwannee River At Ellaville To
Flood Stage By Tuesday. Interestingly, The Alapaha River At
Statenville Has Not Crested Yet And Is Only Now Beginning To Show A
Slower Rate Of Rise. Because We Continue To See Top 4 Or Better
Flows On The Alapaha And Withlacoochee Rivers, We Feel Increasingly Confident That Moderate Flood Stages Will Be Reached Along The Suwannee River At Ellaville And Likely Further Downriver To Dowling Park By The Weekend.
As The Flood Wave Continues Down River, We Expect At Least Minor
Flooding From Luraville Through Branford, Though There Is Potential
Of Reaching Moderate Flood Stage At Branford. However, This Has Less Confidence Than Upriver At Dowling Park. Further Down The Suwannee River, Much Depends On How Backwater Flow Up The Santa Fe River Influences The Suwannee River Crestwave. Moreover, Attenuation Of The Flow Downstream Is Possible Given The Drier Soil Conditions In Place Across Southern Lafayette And Dixie Counties. Thus, It Is Still A Little Too Early To Make A Firm Prediction On Whether Flood Stages Will Be Met On The Lower Suwannee River (Rock Bluff And Beyond).
---Points Still To Crest Or Cresting Now---
Withlacoochee At Pinetta - Moderate Flood Stage
Aucilla River At Lamont - Minor Flood Stage
---Points That Have Crested But Are Still In Flood Stage---
Choctawhatchee River At Caryville - Minor Flood Stage
Choctawhatchee River At Bruce - Major Flood Stage
Chipola River At Altha - Moderate Flood Stage
Flint River At Bainbridge - Minor Flood Stage
Apalachicola River At Blountstown - Minor Flood Stage
Ochlockonee River Near Concord - Minor Flood Stage
Ochlockonee River Near Havana - Moderate Flood Stage
Withlacoochee River Above Valdosta - Minor Flood Stage.
---Flood Outlook For The Suwannee River---
Forecast Confidence Is Now Very High For At Least Minor Flood Stages Being Met At Ellaville And Dowling Park. There Is Increasing
Confidence That These Sites Will Eventually Reach Low End Moderate Flood Stage By The Weekend.
Further Downriver, There Is More Uncertainly But Still A Good Chance
Of Reaching Minor Flood Stage At Branford.
Updated Predicted Crest Ranges And Crest Times As Of 230 Pm Sunday
At Ellaville - 60 To 62.5 Feet (March 9th)
At Dowling Park - 51.5 To 53.5 Feet (March 10th)
At Luraville - 44.5 To 47.5 Feet (March 11th)
At Branford - 31.5 To 34 Feet (March 12th)
