The Coldest Time of Day

By

According to the National Weather Service the coolest time of day in Helena and Great Falls the past week has been at 6:53 am. The sun is rising approximately a minute later each morning. This past week it has been coming up around 6:50.

There are many factors that make certain parts of the day cooler and warmer. The Helena Valley throws forecasters a couple curve balls with the inversion layer that can make the warmest time of day the middle of the night, but if we are not experiencing any kind if significant weather event, the coolest time of day tends be right around sunrise.

Now this may seem like a no brainer because right before sunrise the ground has had the most time to cool since right before sunrise will be the longest amount of time the Earth will go without sunlight.

But…there’s a scientific answer that is a little bit more complicated than that.

The Earth’s surface emits longwave infrared radiation. During the day light hours the surface also gets shortwave radiation from the sun. At night the outgoing radiation from the Earth exceeds incoming radiation from the sun which makes temperatures cooler. It starts getting warmer

Where'd the Long Summer Sunsets Go?

By

                Summer won’t be over for another couple weeks, but this week marks the last of the long summer sunsets. The sun will not set after 8pm again till April 2014.  If you’re pining over the long summer days and wondering, “When was the last time the sun set before 8pm anyway?” it actually was in April.

                The first day of Fall is on September 22nd and is marked by the Fall Equinox, when night and day are the exact same amount of time. Until then, it still is summer, but the shorter days and longer nights are becoming more and more apparent.

                And if you didn’t notice the sunsets were coming sooner and missed one of the last sunsets after 8pm, don’t worry, I shot a time lapse of one for you, just in case.

The Origin of September

By

Today’s weather blog is about the origin of September’s name because it is kind of interesting. Like many things we take for granted these days, the names of all the months came from the Romans. The first Roman calendar was conceived around 56 BC.  The Roman name for September is “Septem” which means “seven”. This probably seems a little weird because September is the ninth month of the year. Don’t worry, the Romans could count. The reason why they called the ninth month of the year “seven” was because when the calendar was first made, March was the first month of the year, making September month number seven in the first Roman calendar.

November and December were the last two months of the year. The 50-ish days between the last day of December and the first day of March were not on the calendar. The time was accounted for, but the days were not recognized in the first version of the Roman calendar.

It took a while, but eventually (in the 1500’s) the Gregorian calendar we used today was put into place. We still use a close version to all the names of the months that were first given more

UV Radition Levels

By

UV radiation levels are going to be higher than normal in several parts of the state tomorrow and this includes the surrounding Helena area. The National Weather Service tracks normal UV levels across the US and provides daily updates on which areas in the country could have higher UV radiation than normal. We are in the yellow in our area. This means the radiation will be above normal during the midday period, but an alert hasn't been issued. If you're outside between 10am and 2pm make sure you wear sunscreen, because when the UV radiation is higher, you can be sunburned more easily.

There are several factors that intensify UV radiation. We have two of them at play in the Helena area. The higher the sun height and altitude the higher the UV level. Helena sits at an altitude of 3,874 feet and the sun is higher in the sky in the summer time.

 

So for tomorrow, remember sunscreen and shade are your friends.

Record Breaking Heat Today

By

Today was HOT HOT HOT! The high in Helena was 96 degrees! We haven’t seen temperatures that high on this day since 1966! Helena didn’t break a record, but it hit the record. The record breaking city was Great Falls. Today the high was 101 degrees. It hasn’t been this hot on this day since 1973 and it was 100 degrees!

The temperatures were high and the humidity was low. The National Weather Service has issued a hazardous weather outlook for today and tonight for fire danger. At one point today the humidity was in the single digits in Great Falls which a critical level in terms of fire danger.

On a lighter note, the temperatures should be cooler tomorrow. Not COLD. But cooler.

The Time is Right for Fishing

By

The Farmer’s Almanac gives people tons of information based on seasonal changes during the year. Once you crack it open, it seems like it can tell you the best time to do anything. It predicts weather, the best days to garden and luckily for us, the best days to go fishing.

                  The phases of the moon are one of the ways to tell when fishing is good or bad. According to the Almanac TODAY is smack dab in the middle of one of the best fishing times of the year. It says when the moon is new and waxing into a full moon is the best time. This will be from August 6th to the 20th.  Since the afternoon thunderstorms have cleared, the rest of the week would be a great time to grab your rod and reel and go fishing.
