00z GFS says rainy Monday for all but some rain Sunday south of the i66 corridor... 00z CMC rainy late Sat into Monday morning
-
Thats why I said FWIW
-
So did the 00z GFS... so...
-
FWIW, 00z CMC slows down, but remains offshore of the west coast of FL as it goes by, makes landfall in the Big Bend of FL
-
lol look at the 00z GFS at 126... decent CAD... 1034mb HP in Quebec...
-
Thats a long time Ian is hanging around Tampa with little movement on the 00z GFS... 30 hours
-
if you choose to accept the 00z ICON, that would be a rainy weekend with maybe a threat for a few isolated tornadoes
-
lol 00z ICON goes for a 2nd landfall at Savannah, GA at 102
-
day 5 NHC has Ian (as a TD) in S NC

Hurricane Ian Discussion Number 16 NWS National Hurricane Center Miami FL AL092022 1100 PM EDT Mon Sep 26 2022 Ian continues to become better organized on satellite images with intense deep convection in its Central Dense Overcast and numerous surrounding banding features. The overall cloud pattern is quite symmetric with well-defined upper-level outflow. Observations from both Air Force and NOAA Hurricane Hunter aircraft indicate that the central pressure is falling, and the intensity is increased to 90 kt based on a recently reported 700 mb flight-level wind of 101 kt from the Air Force plane. This is also in agreement with a subjective Dvorak satellite estimate from SAB. Aside from its relatively brief time passing over western Cuba, Ian will be moving over waters of very high oceanic heat content during the next couple of days. The various Rapid Intensification (RI) indices show a significant probability of RI and this is reflected in the short-term official intensity forecast. However, the SHIPS guidance, which is based on global model predictions, indicates that a significant increase in southwesterly shear and a substantially drying of low- to mid-level air will begin in 24-36 hours. The NHC forecast, like the previous one, shows strengthening to Category 4 intensity in a day or so, followed by gradual weakening. However, Ian is still expected to be a major hurricane when it reaches the Florida west coast. The official intensity forecast is near or above the latest simple and corrected multi-model consensus predictions. Ian continues its north-northwestward trek at about 340/11 kt. The hurricane is expected to move north-northwestward to northward over the southeastern Gulf of Mexico during the next day or so, along the western periphery of a subtropical ridge. After around 36 hours, the track forecast becomes more uncertain, since there is considerable divergence of the track models in the 2-3 day time frame. The guidance also shows considerable slowing of the forward speed, due to a weakening of the steering currents, when Ian approaches the west coast of Florida. This slower forward motion is likely to prolong the storm surge, wind, and rainfall impacts, especially along the west coast of Florida. The official track forecast is adjusted just slightly east of the previous NHC prediction based on the latest multi-model consensus aid, TVCN. Key Messages: 1. Life-threatening storm surge, hurricane-force winds, flash floods and possible mudslides are expected in portions of western Cuba beginning overnight and continuing into Tuesday. Devastating wind damage is possible where the core of Ian moves across western Cuba. Efforts to protect life and property should be rushed to completion. 2. There is a danger of life-threatening storm surge along much of the Florida west coast where a storm surge warning has been issued, with the highest risk from Fort Myers to the Tampa Bay region. Residents in these areas should listen to advice given by local officials. 3. Hurricane-force winds are expected in the hurricane warning area in west-central Florida beginning Wednesday morning with tropical storm conditions expected by late Tuesday. 4. Heavy rainfall will spread across western Cuba through Tuesday. This will likely produce instances of flash flooding and possible mudslides in areas of higher terrain over western Cuba. 5. Heavy rainfall will increase across the Florida Keys and South Florida Tuesday, spreading into central and northern Florida Wednesday and Thursday and the Southeast by Friday and Saturday, potentially causing flash, urban and small stream flooding. Considerable flooding, including significant, prolonged river flooding, is likely across Central Florida.

Hurricane Ian Special Discussion Number 15 NWS National Hurricane Center Miami FL AL092022 500 PM EDT Mon Sep 26 2022 Ian continues to strengthen over the northwestern Caribbean Sea. The last report from the Air Force Hurricane Hunters around 1630 UTC found 700-mb flight-level winds of 79 kt. The inner core appears better organized, and the eyewall structure has greatly improved in radar imagery from the Cayman Islands. The 18 UTC satellite classifications from SAB and TAFB were a consensus T4.5/77 kt, but the continued improvement in satellite structure warrants raising the initial intensity to 85 kt for this advisory. Atmospheric and oceanic conditions remain very favorable for additional intensification during the next 24 h or so, as Ian moves over the very warm waters of the northwestern Caribbean Sea and the southeastern Gulf of Mexico while the shear remains quite low. The NHC intensity forecast calls for Ian to become a major hurricane before it reaches western Cuba early Tuesday. It is then forecast to reach its peak intensity over the southeastern Gulf of Mexico in 36 h. After that, southwesterly shear in association with a deep-layer trough over the eastern U.S. is forecast to significantly increase over the hurricane on Wednesday and Thursday, which will likely disrupt the vertical structure and import drier air into its circulation. Despite these less favorable conditions, Ian is still forecast to remain at or near major hurricane strength as it passes near the west-central coast of Florida on Wednesday and Thursday. The NHC intensity forecast agrees well with the latest IVCN and HCCA aids. Ian has made an expected turn toward the north-northwest, and its initial motion is 330/11 kt. The hurricane will move north-northwestward to northward over the next day or so as it is steered by a mid-level ridge to the east. A turn to the north-northeast with a decrease in forward speed is forecast on Wednesday and Thursday as the center of Ian moves near the west coast of Florida. The slower forward motion is likely to prolong the storm surge, wind, and rainfall impacts, especially along the west coast of Florida. The latest track guidance has come into better agreement on this scenario, although it is noted that small deviations to the shore-parallel track could have large implications on the impacts at particular locations along the west coast of Florida. The NHC track forecast has again been adjusted slightly eastward at 48-72 h, which follows the latest trends in the global model guidance and lies near but just west of the multi-model consensus aids. Based on the latest forecast and timing of expected impacts, Hurricane and Storm Surge Warnings have been issued along the west coast of Florida. Key Messages: 1. Life-threatening storm surge, hurricane-force winds, flash floods and possible mudslides are expected in portions of western Cuba beginning this evening and continuing into Tuesday. Devastating wind damage is possible where the core of Ian moves across western Cuba. Efforts to protect life and property should be rushed to completion. 2. There is the danger of life-threatening storm surge along much of the Florida west coast where a storm surge warning has been issued, with the highest risk from Fort Myers to the Tampa Bay region. Residents in these areas should listen to advice given by local officials. 3. Hurricane-force winds are expected in the hurricane warning area in west-central Florida beginning Wednesday morning with tropical storm conditions expected by late Tuesday. 4. Heavy rainfall will increase across the Florida Keys and south Florida Tuesday, spreading to central and northern Florida Wednesday and Thursday, potentially causing flash, urban and small stream flooding. Significant prolonged river flooding is likely across central Florida.

Decent little outflow boundary coming through on radar

CHO to EZF to S MD get dumped on... 3 to 7 inches of rain through 216 on 12z Euro

LWX AFD from this afternoon: For next weekend, that is where forecast uncertainty greatly increases over our area. Hurricane Ian is forecast to move into the southeast this weekend after landfall somewhere along the eastern Gulf Coast. What Ian does from there is still quite uncertain in terms of the when and where. Some impacts from whatever is left of Ian are possible this weekend though, so monitor the latest forecast for Ian from the National Hurricane Center with more details at hurricanes.gov.
