On the same date every year. Just when we feel like it’s spring, we get another batch of snow.

For those of you who wake up Monday morning to the sight of new snow on your garden, you might be happy to know that new snow is likely to melt on Monday.

Periods of snow or a rain/snow mixture are expected Sunday evening from western central Minnesota through eastern central Minnesota, the Twin Cities metro area, and parts of western central Wisconsin. Parts of northeastern Minnesota, northwestern Wisconsin, and southern Minnesota may also see some snow or a mix of rain/snow at times during Sunday night.

In general, 1 to 2 inches of snowfall is possible in the main glacial range, with the highest accumulations in grassy areas. It is possible that snow will accumulate on roads and highways, and visibility will be reduced Sunday evening during heavy snowfall.

Based on computer models, some areas in the northern part of the Twin Cities metro area could see nearly 2 inches of snow accumulation on grassy areas by 1 a.m. Monday, with 1 inch or less in most of the southern metro. Some snow will melt before weather watchers come out to measure it Monday morning.

You can hear updated weather information for Minnesota and Western Wisconsin on the Minnesota Public Radio News Network, and you can see updated weather information on the MPR News Live Weather blog.

The expected flashes are in the form of knots, with 17 knots equaling 19.6 mph.

Returning to temperatures, metro area heights in the Twin Cities are expected to be around 50 on Tuesday and Wednesday, followed by the lower 40s Thursday and then the upper 40s on Friday.

We can go back to the highs of the 50s next Saturday, with the 60s on Sunday.

Wet Tuesday to Thursday

The slow-moving low pressure system will bring rain in Minnesota and western Wisconsin Tuesday night and Tuesday, with snow in the west and rain in the east on Wednesday. Many areas with rain on Wednesday are expected to see a turn to rain/snow mix or snow mainly from Wednesday night to Thursday.

The National Oceanic and Atmospheric Administration’s Global Forecasting System (GFS) model shows the likely rainfall pattern from 7 a.m. Tuesday to 7 p.m. Thursday:

Severe Weather Awareness Week

According to the National Weather Service:

April 4-8 is Minnesota Severe Weather Awareness Week. More information about Minnesota Severe Weather Awareness Week activities can be obtained from the Minnesota Department of Homeland Security and Emergency Management.

April 4-8 is also Wisconsin Hurricane Awareness and Severe Weather Week. More information can be obtained from the Wisconsin Emergency Management.

The National Weather Service will focus on different topics related to severe weather each day this week:

Monday 4th April – Weather Alerts & Warnings

TUESDAY April 5th – Severe storms, lightning and hail

Wednesday 6th April – Floods

Thursday 7 April – Tornado

Friday April 8 – Maximum temperatures

Here’s the information NWS has posted regarding Monday’s topic, Weather Alerts and Warnings:

hours…
Issued when conditions are favorable for hurricanes, severe thunderstorms, or flash floods. If you are in a lookout area, continue with normal activities but also make plans to seek shelter if necessary.

Warnings…
Issued when severe or impending weather is reported. If you are in or near the path of a storm, seek shelter immediately. Warnings are issued by county and city names. Make sure you know the name of the county you live in and the cities around you.

Advanced info…
The process of forecasting and warning begins one or more days before the time, when the threat area is identified. Hazardous weather forecasts are released early each morning, updated as circumstances dictate.

If a watch is issued…
Local weather offices are equipped with additional staff. State officials are notified and pass the information on to the county and local levels. Provinces and cities are activating their watchdog groups as the threat increases. Television and radio stations convey the word to the public.

If a warning is issued…
Warnings are spread quickly and in many ways, including television, radio and online. Technological advances have allowed people to receive warnings via cell phone, calling, and many other ways. Monitors provide critical storm reports, and emergency officials implement plans made by emergency managers. Updates are released frequently until the immediate threat is gone.

Siren …
Provinces and cities have sirens, and therefore decide how and when to activate them. The National Weather Service doesn’t seem to have them. There are many different policies by counties and cities. Some will activate them throughout the entire county for a tornado warning only. Others will activate sirens across the county for tornado warnings and all severe thunderstorm warnings. Some will activate sirens across the county for severe tornado and thunderstorm warnings of at least 70 or 75 miles per hour. Others will only activate sirens for parts of the interrupts. Also, local officials may sound the siren any time they think severe weather is a threat, even if there is no warning from the National Weather Service.

The siren usually sounds about 3 minutes and then goes silent. It is very rare to keep the siren ringing for the entire warning, as this will cause the backup battery to run out, which is critical in the event of a power outage. Moreover, the siren engine will fail more quickly if the siren is constantly beeping. Some jurisdictions may repeat the siren every few minutes. There is no such thing as “all clear” for storms.

The media…
The media receives and disseminates cautionary information to you, often by interrupting programming. Many television stations use crawling and other visual aids.

NOAA Weather Radio…
NOAA Weather Radio’s Tone Alert feature will activate specially designed receivers, and sound an alarm to alert you of danger. It sounds alert any time the National Weather Service issues a warning, even in the middle of the night. Make sure you have a NOAA Weather radio, as you can’t always rely on sirens, phone calls, or seeing warnings on TV.
