Happy Thanksgiving...

Our holiday should be a beauty...if you're dressed for it. Sunshine with a few high, thin passing clouds will be the rule with low humidity. Temperatures will be rather chilly as a brisk north wind will keep temps mainly upper 50s to low 60s. Some near freezing temps. Friday morning on the Northshore before the warm up begins Friday afternoon. Saturday will see filtered sunshine with hgihs 65-68 and lower 70s on Sunday. Long range still looks iffy for Monday Night Football. Models have flipped-flopped the past 3 days so confidence beyond 3 days is low. Best guess is Monday starts warm 70+ with showers arriving late in the day. Much colder air on Tuesday & Wednesday.

Enjoy the holiday, hopefully with your family & friends, and gear up for Monday Night Football. Go Saints !!! After tonight's Hornet win...Go Hornets Too !!!

Bob,

There are two things for sure. The global warmies will continue to deny the deniers.

AND the SAINTS ain't the "Ain'ts" anymore.

Don't forget to wear ALL black on Monday, even if you aren't going to the game. Bobby Hebert said "You even gotta wear black drawers if you have em".

Saints 35, Pats 21

Happy Thanksgiving to you Bob. Looks like another gulf-low next week possibly. It's going to be stormy. Is this usual for El Nino years to have one gulf low after another? We just had a low move through last week and now another.

Thanks Bob, happy holidays all around, real, blues, caveman, and on. I love this weather. Not too much of a fan of what's coming. But we get the nice stuff again in March. I'm actually excited about a Saints game. I have learned to shrug it off when they lose and be happy they win. But I'm actually excited!

Happy Thanksgiving, Bob and to all that contribute to the discussion on here!

Thanksgiving Day will be fantastic! The secondary Cold Front passed through the NO Metropolitan Area this morning. This will act as a re-enforcing shot of cool and dry air and also bringing the Coldest air so far this Fall. High's today will struggle to get out of the 50's this afternoon and with those winds out of the North at 10-15mph you may need your sweater if you head out. Tonight will be quite chilly with the Southshore dropping into the upper-30's and area's on the North side of the I-12 on the Northshore should see their 1st Freeze tonight. Cover any plants that you think may get damaged by the Freezing Temperatures.

For those of you that are heading out to shop very early tomorrow morning you will certainly need to break out the Jackets because it will be cold. Friday will be quite similar to today except winds will be calm due to High Pressure settling over the area. Winds will shift to the Southeast during Friday Night as High Pressure slides east of our Area. This causes the lows to be slightly warmer than the Night before. The wind shift to the South will also commence a Warming Trend for the Weekend.

Saturday will be a little warmer but will be nothing to complain about. With Mostly Sunny skies, Highs in the Mid-60's, and a Southerly breeze it will be nothing short of perfect.

As a front approaches the area and moisture works back in, rain will come back into the forecast on Sunday. Sunday will also be noticeably warmer with Highs jumping into the 70's. Rain chances will gradually increase as we head into Sunday Night.

Things get tricky here...

The Cold Front will slowly move into the NO Metro area on Monday Afternoon and will then stall Monday Night right over us keeping the area in Rainy Conditions. Meanwhile, Surface Cyclogenesis will be occurring over the Western Gulf of Mexico. Showery weather should continue into Tuesday and the intensity and coverage of the Rain should increase as we move into Tuesday Night. I think it should be noted Temperatures will be in the low 40's(30's on the Northshore) Tuesday Night.

The Surface Low will make its closest approach on Wednesday Morning passing near the Mouth of the River. The Warm Sector looks to remain over the Coastal Waters. Nonetheless, Wednesday will be a Rainy Day (heavy at times), a Cold Day(Highs in the 40's, 50's near the Coast), and a Windy Day with Gusts up to 40mph possible. We may
need to watch for some mixed wintry precipitation as the low ejects out of the area, its not likely but hey, how often is Wintry Precipitation forecasted here when it happens?

Beyond that... The Model Ensembles show Ridging increasing significantly over Western Canada and Alaska. Also, the Arctic Oscillation is plummeting and could reach much lower levels than it did in October (October was the coldest in the Lower 48 in over 115 years). So you know what that means... Buuurrrrrrr!!!

Looks like near freezing temps in viewing area just like the NWS said in the full discussion...

Caveman said...

Just like those that don't believe in global warming they block those that have facts..

Webmaster said...

Nope Caveman, we won't block facts. But we will block you when YOU call out others on this blog.

Perhaps you will see this as picking on you. But this is how we will run this discussion.

Post your facts and we will let others post theirs. But don't call out others by name.

Other posters may do that to you, but you have earned that. You have also earned the right to have us block your posts by your negative comments posted here.

This is our blog not yours.

The NCEP is now officially running the GFSP. The GFSP will replace the GFS in mid December. The GFSP is an upgraded version of the GFS model and should run better as you will read below.

Scheduled: 12/15/2009
Global Forecast System (GFS) Upgrade
Changes include:
-New data sources and improved numerical techniques in the GSI
-Unified post-processor for GFS and GDAS
-Accuracy in formulation of some diagnostic variables improved
-Additional parameters added to products available on FTP servers

You can find GFSP Model runs in the link below...

Darn Southwest Flow! Messing up my forecast bringing in the high clouds earlier than expected. There is a nice ring around the moon this evening! That's because of Ice Crystals in the high Cirrus Clouds which distort the Moon Light. The moon ring is an indication of moisture in the upper atmosphere and that a negative change in the Weather in on the way!
