Severe weather likely for Saturday, calm by Sunday: Working for your weekend forecast
This Saturday, Northeast Ohio is in a region of risk for severe weather, but as the trigger for thunderstorms pushes east, it will leave behind cool, pleasant weather for Sunday. CLEVELAND, Ohio - The perfect environmental conditions for severe storms on Saturday are all lining up and ready to hit: a cold front, deepening low pressure system, and lots of atmospheric moisture to act as fuel to storms. Model forecast: 3 p.m. - 7 pm. of precipitation for Saturday.Kelly Reardon, cleveland.com  But Sunday is a much better story. As the front pushes east it will leave behind significantly cooler temperatures and sunny skies. Model forecast of temperatures this weekend.Kelly Reardon, cleveland.com  Saturday High temperature: 86 degrees Low temperature: 69 degrees Chances of rain: 60 percent in the afternoon through evening Humidity: 65 percent Wind conditions: 16 mph Sunday High temperature: 72 degrees Low temperature: 60 degrees Chances of rain: near zero Humidity: 60 percent Wind conditions: 11 mph The How As the cold front pushes east the moist air ahead of it will produce possible severe strength storms, but will leave behind dry, sunny skies for Sunday.Kelly Reardon, cleveland.com  A very strong cold front is expected to pass through Northeast Ohio bringing in plenty of rainfall and heavy storms for Saturday. Why? Cold fronts are the perfect trigger for thunderstorms because they cause rising motion in the atmosphere. As air rises it becomes unstable as is cools to its dew point forming condensation and rain. But there's more. This weekend a deepening low pressure system is yet another trigger for thunderstorms, and with heavy atmospheric moisture to support development storms could become fairly strong. The Storm Prediction Center has us in a region of slight risk for severe weather Saturday, so make sure to have government alerts enabled on your smart phone so you can be notified of any warnings from the National Weather Service.

Weather quiz Wednesday: Remote sensing of the atmosphere
Take the quick 10 question quiz to test your skills on remote sensing. CLEVELAND, Ohio -- Remote sensing is one of the most important tools that meteorologists and all kinds of scientists use to view atmospheric, oceanic, and land use changes. But how much do you understand about how it works? Take the quiz to find out! Answers Explained: 1.The first satellite launched into space was Sputnik I on October 4, 1957. 2. GOES is a Geostationary Operational Environmental Satellite which stays in one area with respect to Earth, meaning it moves at exactly the same speed as Earth. 3. As above, geostationary means the satellite does not move with respect to Earth as it rotates. 4. POES (or a polar-orbiting environmental satellite) rounds the Earth 14 times in one day. 5. The benefits of infrared images are that they can tell the difference between high clouds and low clouds, whereas on a visible image it's hard to decipher the difference. Also, visible images are only available during the daytime in that location, infrared images are available 24/7. 6. Water vapor is the gaseous form of water, and is very important for meteorologists to see where heavy moisture is available to support storm development. 7. Imagine the atmosphere is a moist towel, and a bucket is a column of air. Precipitable water would be the depth in that bucket if all the water in that towel were squeezed out (all the water vapor in the air precipitated out by rain). 8. Satellites both ingest surface observations of wind speeds (for surface winds) and track the movement of clouds for wind speeds higher in the atmosphere. 9. ASOS stands for Automated Surface Observing Systems and is an automated device which takes temperature, dew point, humidity, cloud cover, any many more measurements sometimes every minute. 10. Remote sensing has many applications, not just for meteorology. It is important for climatologists, oceanographers, geologists, almost every science application.

Check out this weekend's weather forecast for Northeast Ohio. Daily high temperatures through Monday.Kelly Reardon, cleveland.com  CLEVELAND, Ohio - A very spring-like weekend is ahead for Northeast Ohio. Through this evening, winds will remain a bit gusty, but skies will stay mostly sunny with warm temperatures. The rain begins Saturday and will continue through Monday, but so will the temperatures in the 60s. Pollen will be at a low-medium level through Sunday, but the sniffles may return Monday as it peaks at a medium level.

Through Monday, it's a tale of passing low pressure systems, and persistent southerly winds keeping temperatures nice and warm. Saturday and Sunday, a low will slowly creep across the region bringing in rain, and eventually thunderstorms. Monday, another low pressure system will move on through. Low pressure triggers the first ingredient in showers - lift in the atmosphere. As the air rises, it becomes very unstable, eventually forming condensation and rain.

Another day of 60-degree weather: Akron weather forecast Monday, Feb. 20
Check out the weather forecast for Akron on Monday. AKRON, Ohio - The warm weekend weather in Akron will thankfully last through Monday to kick off the week. The high temperature will reach 61 degrees, which is still 6 degrees behind the record set in 2016.

High pressure causes sinking motion in the atmosphere, which leads to the air drying out significantly becoming very stable. Since rain and snow showers need moisture and instability to form, this is why chances are so low.

Further cool down expected today: Cleveland weather forecast Thursday, Feb. 16
Check out the weather forecast for today in Cleveland. CLEVELAND, Ohio - That's right, Cleveland, although we've had some nice warm days this week, we are expecting another day of a cool down. This afternoon, temperatures won't top above 30 degrees, but with calm winds, wind chills won't be too bad.

Why is Northeast Ohio getting thunderstorms in February?
Meteorologist Kelly Reardon explains how Northeast Ohio is getting thunderstorms in February. CLEVELAND, Ohio -- Northeast Ohio has been experiencing plenty of rain, with some thunderstorms, since early this morning, and they're not expected to slow down anytime through the rest of the day. But, thunderstorms in February? It's definitely not a common occurrence, so let's look at how this is happening. First, for thunderstorms in the winter in general, you of course need warm temperatures, otherwise we'd be experiencing snow. Today, not only did a passing warm front ramp up temperatures, but very strong southerly flow is dragging in that warm, moist air from the Gulf. Ohio is so flat, that almost any day winds are out of the south, that warm southern air invades the region. Temperatures might reach so warm, in fact, that Cleveland could reach the 60-degree high temperature record set back in 1925. Right now the high is forecasted to reach just 58 degrees, but we're close enough to where a tied record is possible. The second most important ingredient in thunderstorms is a source of instability. That warm front is easily one source, as this pushes the colder air ahead up into the atmosphere. As the air moves upward, it cools to its dew point, forming condensation, plenty of rain, and this in turn increases its instability. But the warm front isn't the only lifting source in the atmosphere, a low pressure system is also doing the same -- so it's basically a double whammy for instability, allowing rain showers to grow strong enough to produce lightning. This happened not too long ago, back in mid-January, with a similar atmospheric setup: strong southerly flow and a passing low pressure system. Why are winter thunderstorms so rare? And why is Cleveland getting them in January? What do you think of this weather? Do you prefer the warmth with some rain, or would you rather the cold and snow?

Dry tonight, summer-like Tuesday: Northeast Ohio weather forecast
Tuesday temperatures are ramping up to the low 80s for a summer-like throwback. CLEVELAND, Ohio - Who's ready for extremely hot temperatures for Tuesday? Not me. Tonight is expected to stay cool, but Tuesday is going to feel like mid-August. Tonight: A warm, dry evening is in the forecast tonight. At 8 p.m. temperatures will cool to the mid 70s and will drop to 70 degrees by 11 p.m. Skies are expected to be cloud free, so therefore there's no rain chances to worry about. Tuesday: Tuesday is going to feel like a throwback to summer. Temperatures will sky rocket to 84 degrees between noon and 6 p.m. The average high temperature is 72 degrees - we're going to definitely pass that. But the record? 92 degrees. Let's not jinx it. Hourly temperature forecast for Tuesday.Kelly Reardon, cleveland.com  Dew point comfort scale.Kelly Reardon, cleveland.com  But, at least the morning will be cool in the mid 60s. Skies will be partly cloudy, but no rain chances are expected all day. Humidity is also going to be very low, with dew points in the high 50s to low 60s. Sunrise: 7:13 a.m. Sunset: 7:27 p.m. Pollen forecast: Ragweed, chenopods, and nettle will be at a low-medium level of 4.6 for Tuesday. Lake conditions: The National Weather Service is reporting west-southwest winds at 8 mph with waves less than 1 foot. Tuesday evening, they are forecasting east winds around 7 mph with waves still less than 1 foot. The How: A very broad area of high pressure will stick around for Tuesday keeping rain chances near zero and cloud cover very low. High pressure causes sinking motion in the atmosphere, which basically dries air out like squeezing out a moist towel, and makes it very stable. Without moisture not a single thunderstorm can initiate, so sunny skies are in the forecast instead.
