Interesting disco tonight Tropical Storm Gamma Discussion Number 11 NWS National Hurricane Center Miami FL AL252020 1000 PM CDT Sun Oct 04 2020 Gamma has moved much farther northeast than previously anticipated. With little in the way of low or mid-level large-scale steering flow currently in place, it seems likely that upper-level southwesterlies, also responsible for the shear affecting the tropical storm, are causing this recent northeastward motion. This may be either through reformations of the center closer to the convection or a direct contribution to the net steering. An Air Force Reserve Hurricane Hunter aircraft is currently investigating Gamma and so far has found max SFMR winds of 47 kt but flight level winds of only 45 kt. Given the data so far, there is no indication that Gamma is any stronger than the 50 kt intensity, but it seems prudent to let the plane finish its pattern before lowering the winds at this time. Gamma's future track is highly uncertain. The track guidance spread is much higher than usual, and confidence in the forecast is accordingly low. Most of the global models indicate that Gamma will soon begin moving generally west-southwestward as a mid-level ridge briefly builds over the eastern and central Gulf of Mexico. Unfortunately, there is little agreement on exactly when this will happen or how fast Gamma will move once it turns. After about 48 h, Gamma could interact with Tropical Depression Twenty-Six, which is forecast to move over the northwestern Caribbean Sea at that time. Current dynamical models are notoriously bad at forecasting such interactions, but if the two systems do interact it will likely cause Gamma to move inland over the Yucatan. Whether such an interaction occurs or not, continued shear and proximity to land should cause the tropical storm to gradually weaken, and Gamma could dissipate if it moves over land (and stays there) in a few days, as shown by the GFS. The ECMWF shows the vortex remaining over water but dissipating nonetheless, while a couple other global models maintain the vortex longer and show it moving north over the central Gulf of Mexico late in the forecast period. The NHC forecast is a compromise between those solutions, showing a remnant low moving north over the southern Gulf of Mexico by day 5. In general, the NHC intensity forecast is similar to the previous one, but slightly lower to account for the system potentially moving inland. Due to the uncertainty in the forecast at this time, future advisories may feature larger than normal changes to the track or intensity forecast. It is also worth noting that several dynamical model trackers appear to lose Gamma and jump to tracking Tropical Depression Twenty-Six when it reaches the Gulf of Mexico, resulting in unrealistic depictions of the intensity and track forecasts. KEY MESSAGES: 1. Gamma is expected to produce heavy rainfall for several days over portions of southeastern Mexico, the Yucatan Peninsula, Central America, and far western Cuba. This rainfall could result in life-threatening flash flooding and mudslides, particularly in the mountainous regions of southeastern Mexico and Central America. 2. Even though Gamma is just offshore, tropical storm conditions are likely along portions of the northern coast of the Yucatan Peninsula on Monday.

Tropical Storm Gamma Discussion Number 3 NWS National Hurricane Center Miami FL AL252020 1000 PM CDT Fri Oct 02 2020 A few hours ago, the Air Force Hurricane Hunters found maximum winds of around 35 kt in the northeastern quadrant of the cyclone, which was the reason why it was upgraded to Tropical Storm Gamma. Since then, there have been no stronger winds reported so the initial intensity remains 35 kt. The minimum pressure estimated by the aircraft is quite low at 998 mb, so it seems likely that the winds will increase soon. The storm also has better banding features compared to hours ago and deep convection has also been persisting near the center. Fixes from the aircraft indicate that Gamma has jogged to the left recently, but smoothing through the short-term jog suggests an initial motion of 310/8 kt. The tropical storm is expected to remain on the western periphery of a subtropical high during the next couple of days, and that should cause the storm to move slowly northwestward during that time period. This track should take Gamma across the northern Yucatan Peninsula and perhaps over the extreme south-central Gulf of Mexico this weekend. By early next week, a mid-level ridge is expected to build to the north of the storm while another low pressure area is forecast to develop to the east of Gamma. This change in the steering pattern is expected to cause the storm to make a sharp left turn toward the Bay of Campeche, but continue to move at a fairly slow forward speed. The models have shifted well to the south from 48-120 hours this cycle, and the NHC track forecast has been adjusted in that direction. Despite the shift, most of the reliable models are south of the new official track forecast, and future southward adjustments could be necessary. Environmental conditions appear generally favorable for additional strengthening until the cyclone reaches the Yucatan Peninsula on Saturday, and the NHC intensity forecast shows a slightly higher landfall intensity there. Once the system moves over the Yucatan Peninsula and the extreme southern Gulf of Mexico, the combination of land interaction, an increase in shear, and drier air should limit the amount of strengthening into next week. At this point, no model shows Gamma becoming a hurricane, and the NHC intensity forecast shows little change in strength for much of the forecast period. The biggest threat from this large and slow-moving storm is the the potential for heavy rainfall and flooding, particularly near and over mountainous terrain. KEY MESSAGES: 1. Gamma is expected to produce heavy rainfall that could result in life-threatening flash flooding over portions of the Yucatan Peninsula, far western Cuba and well away from the center in the Mexican states of Campeche, Tabasco, and northern Chiapas. 2. Gamma is forecast to bring tropical storm conditions to portions of the Yucatan Peninsula on Saturday, where a Tropical Storm Warning is in effect.

DISCUSSION AND OUTLOOK ---------------------- At 1000 PM CDT (0300 UTC), the center of Tropical Storm Gamma was located near latitude 19.1 North, longitude 86.1 West. Gamma is moving toward the northwest near 9 mph (15 km/h). A slower northwestward motion is expected during the next couple of days, followed by a turn to the west or west-southwest. On the forecast track, the center of Gamma should be near the northeastern Yucatan Peninsula on Saturday. Maximum sustained winds are near 40 mph (65 km/h) with higher gusts. Some strengthening is expected before Gamma moves inland over the northeastern Yucatan Peninsula on Saturday. After landfall, slight weakening or little change in strength is expected. Tropical-storm-force winds extend outward up to 45 miles (75 km) from the center. The estimated minimum central pressure based on data from the Air Force Hurricane Hunters is 998 mb (29.47 inches).

You guys always have the best gifs/images I know you guys kept the toaster of failure that I think Forky made up? Along with his salad shooter of success?

Too bad clouds and showers will block our view tonight

I'm guessing that's supposed to be a blizzard sounding?

Wow

Wow at the bolded in teh afternoon AFD... 5" of rain in 90 mins -- but unofficial for now Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 228 PM EDT Thu Sep 10 2020 .SYNOPSIS... A cold front will drop south of the area through the first part of the weekend, then return northward as a warm front Sunday. Another cold front will likely impact the area early next week. && .NEAR TERM /THROUGH TONIGHT/... A surface trough between an approaching cold front from the west and a tropical disturbance offshore has resulted in a band of heavy showers and thunderstorms right up and down I-95 from near Laurel, Maryland, through the immediate Washington DC metro area southward into western Charles County, Maryland. Additional showers and thunderstorms will likely develop on either side of this axis through nightfall, with additional flash flooding likely. Rainfall amounts (preliminary, unofficial) of up to 5 inches have been reported in a span of 90 minutes. This is occurring due to deep, abundant tropical moisture with PWs near 2.5 inches and high/deep warm cloud layers. Activity should gradually diminish this evening, though some local expansions/extensions of the Flash Flood Watch may be necessary. Remember, do not drive around barricades or across flooded roadways. Some patchy fog and drizzle is likely overnight with a moist atmosphere and not much wind as the front sits overhead.
