Fall 2015 Pattern Discussion


Recommended Posts

We could use every drop of that rain eastern NC will get over upstate South Carolina. According to the GFS though, our area will get .25 at best right through day 16. i'm starting to think the southern US from Cal to the Carolinas will be very dry this fall and winter despite Elnino.

I think this is common to be dry early in Fall during el ninos. Usually things get cranking from November onwards.

Potential 5 days of rain...

.LONG TERM /THURSDAY THROUGH TUESDAY/...AS OF 300 PM TUESDAY..HIGH CONFIDENCE IN A HYBRID CAD PATTERN SETTING UP ALONG THE EAST COAST WHICH PROMISES TO PROVIDE SOME MUCH NEEDED SIGNIFICANT RAIN OVER THE AREA THROUGH THE WEEKEND. PROLONGED EASTERLY FLOW WILL PROVIDE MOISTURE ADVECTION AND ISENTROPIC LIFT WILL BE ON THE INCREASE ON THE 300K THETA SURFACE...WITH INITIALLY PATCHY RAIN THURSDAY BECOMING WIDESPREAD ON FRIDAY AND LINGERING THROUGH SUNDAY. WILL INCREASE POPS A NOTCH...WHICH WILL LIKELY BE RAISED FURTHER WITH ENSUING FORECASTS. THE POPS AND RAINFALL AMOUNTS WILL BE WEIGHTED HEAVIER IN THE EAST...BUT AMOUNTS ARE LIKELY TO EXCEED ONE INCH EVEN IN THE FAR WESTERN CWFA GIVEN THE DURATION OF THE EVENT AND POTENTIAL FOR PERIODS OF HEAVIER RAIN AS UPPER SUPPORT FROM PERTURBATIONS IN THE MID LEVEL TROF LIFT NORTHEAST. HIGHS WILL SHOW THE USUAL CLIMATOLOGICAL CAD PATTERN...GENERALLY RANGING FROM UPPER 60S NORTHWEST TO MID 70S SOUTHEAST...WITH MINS IN THE UPPER 50S TO MID 60S. STEADY RAIN WILL TAPER TO LINGERING PATCHY LIGHT RAIN AND DRIZZLE ON MONDAY AS THE SUSTAINED COOL AIR ADVECTION IS CUT OFF AS THE SURFACE HIGH MOVES OFF THE NEW ENGLAND COAST...ALLOWING THE SURFACE LOW TO LIFT OUT. TEMPS MONDAY SHOULD BE A SHADE HIGHER...MID TO PERHAPS UPPER 70S...WITH TUESDAY LOOKING TO BE DRY WITH HIGHS 75 TO 80.

Well, not only would we get five days of depressing rain during the time of the year when it is usually great to be outside, but we'll probably miss the lunar eclipse, too.

 

We need the rain, we avg roughly 5" of rain in Sept and we have under 1" so far.  This weekend could catch us back up.

What kind of garden and lawn are you supposed to have in fall and winter?

You can grow plenty of things in the fall: sweet potatoes, peas, lettuce , cilantro , garlic, and many others ! Flower wise: snapdragons, pansies, fall blooming camellias need water, violas, etc! And it's the best time of the year to plant trees and shrubs and your fescue lawn, if you have one, will look the best it ever will over the next 4-5 months. So we still need rain in fall and winter and even though deciduous trees and shrubs are dormant, they still need water.

Really, 18z GFS?  4.84" through Sunday for RDU? At the same time, KJNX only gets 1.80". (heaviest appears to fall just N&W of here). Going to be a fun 5 days to follow and observe - that's for sure. Reminds me of a deformation band in a snowstorm. Even if it is 'just plain rain (Brick)', it's quite an interesting event through the weekend. Considering we've had NOTHING to observe all Summer, I'm going to enjoy watching this unfold --- or even fold.

More like 3-4 in my area down to the lowcountry. I am certainly with you, its been too dry for way too long. At least its alot cooler here today.

 

From the 12z Euro run, it had a heavy slug of moisture tracking through the Midlands from the Atlantic to give the much higher numbers.  Without that, it'd still pretty dry with normal light rain showers.  Something tells me that the heavy won't verify on the operational run.

 

The 12z EPS has a mean of under two inches through the period if that tells you anything.  Of course, there are quite a few members around 2-3 inches within a few days... enough of them to guess that's about all we could hope for around CAE.

 

Per 18z (I have technical issues with my provider) the GFS is around an inch or less for us here.

 

If I had to give a number, I'd say 0.75-1.00 inch through this "wet period"..... and even that could be wishful thinking for some of us not in the right spots.  :(  Haven't had any real good rain imby for quite a while now... been seeing the rain close by.. just no cigar.

 

 

Edit: on a side note.. i've been telling people that they might get sick of rain later on in the year with the El Nino.  Hope it works out and we all end with a surplus.  I'm still kinda down over last year's great analogs and overall a let down for most though... I don't trust anything currently.
