Strong Fall Cold Front To Sweep Through Southeast AU

Written by Meteo Expert Josef Lukas

A potent cold front will cross southeast Australia on Friday and Saturday with strong winds accompanied by gusty showers and thunderstorms.

Weather outlook for Friday and Saturday

The Details

Low pressure will organize across the Bight on Thursday and then begin to affect the southern SA coast with gusty thundershowers on Friday.

The strong winds and thundershower risk will arrive in Adelaide Friday afternoon and in western VIC Friday night. Melbourne’s risk for strong winds and thundershowers will occur during the day on Saturday.

As the cold front moves across southeast Australia, winds are expected to gust between 60-100 kph for many areas, including the Melbourne metro area. Across the Bass Strait and VIC Alps, wind gusts will approach 120 kph at times.

Expected wind gusts Friday and Saturday

Gusty showers will linger across VIC and TAS on Sunday, however, the most potent part of the storm will have exited to the east.

Severe Thunderstorms Threaten Buenos Aires, Montevideo on Wednesday

Written by Meteo Expert Josef Lukas

There is a significant risk of severe thunderstorms across Argentina and Uruguay on Wednesday. Damaging winds, large hail, and flash flooding are all possible. Additionally, frequent cloud-to-cloud and cloud-to-ground lightning is expected.

Chances for severe weather on Wednesday

The Details:

A cold front will push northward across Argentina on Wednesday and run into a hot and unstable air mass across central South America. Moisture from the Atlantic Ocean will get drawn toward the cold front and help ignite heavy, severe thunderstorms.

The severe weather setup on Wednesday

The major metropolitan areas of Buenos Aires and Montevideo have the greatest severe risk potential Wednesday afternoon and evening. Damaging winds in excess of 80 kph and large hail of 2-4 cm in diameter are possible.

Another concern with these storms is the potential for flash flooding. Rainfall amounts of 25-75 mm are expected within the thunderstorm threat area over a short period of time, leading to areas of flooding.

The severe weather risk will shift northward through Argentina and Uruguay Wednesday night.

Cooler and drier air will move into Buenos Aires and surrounding areas later Wednesday night and during the day Thursday.

Keni Acquires Severe Tropical Cyclone Status; Batters Fiji

Written by Meteo Expert Josef Lukas

Cyclone Keni strengthened into a severe tropical cyclone on Tuesday. Keni is expected to batter Fiji with heavy rain, damaging winds and coastal flooding Tuesday into Tuesday night.

In anticipation of the storm, the Fiji National Disaster Management Office briefed government officials and tweeted out a statement saying they are prepared for the cyclone.

Cyclone Impacts

Keni is expected to drop between 50-100 mm of rain on the northwest side of Fiji’s largest island, Viti Levu. The southeast side of Viti Levu will see less rain because of downsloping winds from the mountains in the middle of the island.

Winds of 80-100 kph are expected across Viti Levu, particularly across the southern part of the island which will be closer to the central of the cyclone.

The good news for Fiji is that Keni will be a quick moving cyclone. On Wednesday, some sunshine will return to the area as Keni marches southeast away from the country.

 

Keni is the seventh named cyclone of the South Pacific cyclone season, which runs from November 1st to April 30th each year.

Large Hail, Gusty Winds, and Tornadoes Rake the South on Friday!

Written by Team Morecast

 

Severe storms rumbled across portions of the Mid-South on Friday, producing high winds, large hail, and a few tornadoes as well (see radar animation and storm reports above). Here is some vivid video evidence of the large hail, received via Twitter.

 

 

In the end, the SPC (Storm Prediction Center) counted 145 total severe weather reports, including 92 hail, 43 wind, and 10 tornado. The largest hail reports came from the suburbs on the north side of the Dallas-Ft. Worth metro area (see above), up to three inches in diameter. Fortunately the pattern calms down in the next few days with no significant chances for severe storms in the foreseeable future.
