Your 2021 Weather Predictions (snow, hot, warm, recorded)

[B87]

What are your weather predictions for the year ahead where you are?

For here, I get the feeling it'll be a shocker.




January: the month continues as it has done, with below average temperatures and barely any sun. The month takes the title of cloudiest January on record.
February: continues where January left off. A heavy snow event in the first week brings 15cm to London, but the skies remain mostly grey. When the sky does clear, minima crash to -7c.
March: yet more of the same; cold both day and night with frequent rain and barely any sun or signs of spring.
April: no sun recorded for the first 15 days of the month, accompanied by rainfall and cool temps. The 2nd half brings almost unbroken sunshine with temperatures frequently around 20c.
May: mostly warm, dry with partly cloudy skies. A brief heatwave late in the month produces the first 30c in May since 2005.
June: continues where May left off; mostly sunny skies and temps above 30c in the first few days. The 2nd half of the month is frequently cloudy and cool.
July: A mix of partly and mostly cloudy skies and average temperatures. A plume event mid-month peaks at 35c, but the end of the month is cool, cloudy and dry.
August: very cool, cloudy and dry for the first 3 weeks. The final week is warm with unbroken sunshine, and produces the first above average day of the month.
September: continues warm and sunny as August left off. A 2nd plume brings 30c and some thunderstorms, but the month closes mostly fine and settled.
October: the UK is repeatedly battered by the remains of Atlantic hurricanes. The month is characterised by almost non-stop rainfall and cloud, becoming the wettest month ever recorded.
November: another very mild, wet and cloudy month.
December: frequent winter storms bring plenty of rain, but also allow for the sun to appear in between. A mild and wet month with near average sunshine.

Here they are for 2021 for my area

January - Has been above average, snowless, and dry so far. Second half of the month will be colder and rainier with one snow event that won’t stick around long due to the models not showing extreme cold due to the -PNA. This combines for an about average January, both temperature and precipitation wise.
February - Models show -PNA and a nice SE ridge, so this will be a warm, snowless month generally except for maybe the first week, when there could be a dusting of snow, sleet, and freezing rain.
March - Slightly above average temperatures with about average precipitation. March is on average our wettest month of the year. Some wet snow in the first week which melts quickly. Then, generally springlike with 50s and 60s everyday and some warmer Nor’easters and thunderstorms.
April - Comfortable and mild. Slightly above average temperatures and precipitation with more thunderstorms than average. Active severe setup predicted for the Midwest and Mid-Atlantic, but generally nice and pleasant.
May - One of the best months of the year as May often is here. Slightly above average temperatures and slightly drier than normal, but the first half of the month will be active in terms of thunderstorms. Then settling into a dry pattern in the latter half. First 90+ in the last week.
June - High pressure dominates, and a dry month results, with slightly above average temperatures. First heat wave in the middle of the month with a week of 90s, but not humid due to the high pressure. No rain recorded on the last 18 days of the month.
July - Heat wave in the early part of the month with hot and dry conditions and temperatures reaching 100 twice. Drought conditions with no rain recorded from June 12 to July 9. The rest of the month is generally cooler and wetter than average, but there is another heat wave.
August - Slightly below average temperatures and average rainfall. Similar to latter part of July.
September - Continuation of August for most of the month, then a cool down later with some pleasant 70s and sunny weather.
October - Generally wet, with a tropical storm in the beginning of the month producing the most flooding of the year, along with high winds. Then nice fall weather consistently in 60s.
November - Slightly cooler version of October with a few still warm days. Average month.
December - Slightly above average temperatures average precipitation. Snow event around the 10th. First freeze Dec 5. Christmas week is cool and cloudy.

Is that the only mantra you have for weather predictions?

La Nina signal will start kicking in more, given the PNA switch. That will allow for a warmer and drier back half of winter then through spring in the southern half of the US. The subtropical ridge will then move farther north, allowing a robust summer wet season in the Southern US, as well as the Desert Monsoon region. The following fall and winter will continue the mild and dry pattern, assuming the La Nina remains a fixture.

I told ya guys last year we are gonna be in a 3 year dry spell for my area. Anytime you have a west flow all summer my coast does not get rain. Plus this winter is gonna be super dry as should be with a La Nina. What about your every place is sub trop and sub this?

'Dry' when you average almost 1200mm of rainfall per year?

I had under 29" last year. While most of south FL had 80"+. Living right on the gulf with a west flow all summer means very little rain. I avg more rain in the winter most times. North FL as well as inland had 45"+. Tampa was below normal for rain as well as most any place right on the gulf. This will also be a very dry year for my area since with a La Nina i get more of a west flow during the summer. I am counting on under 30" again this year.

30" isn't dry.

I expect we'll continue our average of 296 days of sunshine throughout 2021.
