With this being our first threat for severe weather this season (albeit a low risk) and tomorrow the start of the NWS Spring Safety Campaign we wanted to share a quick tweet thread about Severe Weather Preparedness and other basic information! (1/7)
First off as we go through March to June you will be seeing more and more of these @NWSSPC Outlook Categories. Today's risk is the lowest: Marginal, or Risk 1 of 5. It means that there may be a few isolated severe storms possible. Check out the graphic for more information! (2/7)
Severe Thunderstorms can produce several different Hazards like, tornadoes, & damaging winds. The protective action for most of them is to move indoors and away from windows. If you want to learn more check out our 6 remaining Skywarn Talks! weather.gov/ewx/skywarn (3/7)
Probably the most important action to take ahead of Severe Weather Season is to have multiple ways of being notified of severe weather. This includes WEA messages, Local Jurisdiction Notifications, TV/Radio, The Internet, NOAA Weather Radio, Weather Apps and more! (4/7)
Once you receive an alert from one of those methods from the last tweet it is important to know what it means. In general a Watch means to be prepared and that severe weather is possible, while a Warning means the dangerous threat is imminent and to take action NOW! (5/7)
While the overall threat is of Severe Weather is low tonight, storms that do form could produce hail. We've seen folks commenting that they are going to put their cars in the garage, just in case! Excellent preparedness! Check out these graphics for more on hail! (6/7)
If you do get hailed on today or any day and can safely report it to us you can use #ewxspotter here on Twitter. Include 3 things: The time it occurred, the Event - so the size of the hail, and the Location - where are you? Bonus points if you include a picture! (7/7)

A historic winter weather week continues. Patchy freezing drizzle will redevelop late tonight and could cause some problems on roadways across our northern counties. Saturday afternoon and evening, additional light freezing rain and sleet may exacerbate these issues. 1/x
It only gets worse from there. Sunday evening, a wintry mix will develop, and as temperatures plummet a changeover to snow will occur with accumulations expected in many areas. 2/x
Travel Sunday night into Monday will be difficult if not impossible as winds increase and whip around the snow, reducing visibility. Additional power outages could be possible. 3/x

Meteorologists at 92 locations in the US and its territories and many others worldwide have launched weather balloons twice a day, every day for many decades. Here's one example of how the process typically works, made a while back by @NWSTampaBay: 2/5
Recently, a system was developed that automates the process and can be controlled remotely. @NWSFairbanks shows one off here: . There is also some additional info here: bit.ly/2SOHgF4 3/5
