Solar Eclipse for Cleveland Ohio

Cleveland Nation Weather Forecast for the 2024 Solar Eclipse.


All your up to date forecast and information for the Solar Eclipse.

solar eclipse happens when the Moon passes between the Sun and Earth at just the right moment. Sometimes, the Moon only blocks part of the Sun’s light which is called a partial solar eclipse. Other times, the Moon blocks all of the Sun’s light which is called a total solar eclipse. As the Moon blocks the Sun’s light, it casts a shadow on part of the Earth. The Moon’s shadow creates a trail as Earth rotates, and this trail is called the path of totality. Places in the path of totality will experience total darkness during an eclipse since the Moon completely blocks the Sun's light for a few minutes resembling night time.

On Monday, April 8, 2024, a total solar eclipse will cross North America. The eclipse will pass over parts of Mexico, the central and eastern United States, and southeastern Canada. The path of totality will first enter the United States in Texas, then pass through Oklahoma, Arkansas, Missouri, Illinois, Kentucky, Indiana, Ohio, Pennsylvania, New York, Vermont, New Hampshire, and Maine. Cleveland, as well as much of northern Ohio and northwest Pennsylvania, will experience totality during the mid afternoon. Cleveland will experience totality between 3:13 and 3:17 PM EDT.

Severe Weather Possible

Good evening folks. After a weak cold front moved through northeast Ohio earlier today bring mostly clouds and very little precip with it. A ridge aloft is already building into the great lakes region. High pressure will be building off the East Coast allowing for a return flow out of the southwest  to develop by Thursday morning.  Winds will be gusty. A warm front will than try to push northward during the day. Current models bring the warm front just north of Lake Erie. Winds around H925 will be increasing to around 55kts. This combined with breaks in the clouds will allow the winds to reach the surface. This will have to be watched. The cold front will than reach the region late in the evening.

Latest guidance continues to show the threat for severe storms across the region. SPC has the area in a slight risk form around the I-70 area and south. This seems correct based on the amount of snow cover north of that area that will help limit severe weather and how warm the temps get.


 

Looking at the latest model data and it is still showing the LLJ(low level jet) increasing during the evening(which is when the LLj is the most active) which will help keep the storms going. This will also lead to shear. This may cause a few spin up's along the QLCS(Quasi-linear convective system ). We will most likely a damaging wind threat more than anything with this system.
As you can tell in the second picture that the LLJ continues to get stronger as the night goes on. This will lead to more wind damage.
Shear values will be also good for a few isolated spin up's also. We will need to watch this closely tomorrow.
Another thing we will have to watch is the winds at H500. They will be strong and this will allow for divergence aloft which will aid in developing the storms. We will also have to watch the vort max as that will also aid in some enhancement in the storms.
Last but not least is the amount of rain we will see. The map below is a 3hr rainfall total map. As you can tell there will be a lot of rain with these heavier thunderstorms.  This combined with snow melt will lead to rapid flooding. There are flood watches already issued for parts of Ohio.
So overall expect to see temps increasing to the upper 50s across southern Ohio and lower 50s across northern Ohio tomorrow. There could be a few showers with the warm front passage. Make sure you are weather ready with your NOAA weather radio..and emergency kits incase you lose power or you need to take shelter. Make sure you stay up on the latest with the local NWS or TV stations.

Snow and Warmer Temps

Another a low pressure system effects southern Ohio this evening and into the over night, we will than turn our attention over to a warm up that will effect the eastern US over the next week. Computer models are coming together in bring a major warm up to the Ohio valley. Back to the current snow that is falling right now in Southern Ohio.

Latest guidance continues to show decent snow fall amounts from Cincy and down south into Northern Kentucky. Here is what the latest HRRR model is showing. A good 3-6 inches of snow will fall between now and late tonight. The evening rush will be terrible. We will see snow fall rates around 1 inch an hour. The mostly likely place to see the heaviest snow will be Northern Kentucky and Southern Ohio.


The snow will be ending after midnight for most areas. High pressure will be building in on Saturday before another clipper effects the region Saturday night into Sunday. However the snow will be light with amounts around an 1 most places.

After that we than turn our attention to the warmer weather. The latest WPC forecast for Thursday... I still think that they are going to warm with all the snow pack that is currently across the Eastern US. The cold front will sweep across the area Thursday night into Friday. There could be some thunder storm around but its to early to put into the forecast right now. Will continue to updated as the week goes on.

Extreme Cold Coming to the Ohio Valley

After a rainy Sunday across southern and eastern Ohio we will be watching for extreme cold to effect Ohio starting Monday and continuing into Wednesday. We will have wind chills as low as -40 for Tuesday morning so make sure you stay warm.

Here is 7 AM Monday showing the colder air arriving behind the low pressure system.
As you can tell the temps will be dropping Monday as the arctic front moves through. By 7 PM Monday evening the temps will already be in the negatives. 



Tuesday morning will be the coldest. Wind chills will be below -40 so expect a lot of school closing. 
And just the heck of it here is the 850MB temps for Tuesday morning...haven't seen these temps since 1994.

 After the brief cold shot we will start to warm things back up. The next shot of snow will be Thursday. After that winter takes a break for a few days with temps climbing back into the 40s.

4/19/13 - A Temperature Roller Coaster Ride

Article By:  Lester Rhoads
Ohio Weather Blog Long Range Forecaster



We've been on a temperature roller coaster for the last several weeks and that looks to continue as we go through the rest of April and into May.  We were in the low 80s in Cincinnati yesterday and the low 40s today with even a few sleet and rain showers this evening!  What a change...  Well what are a few of the factors driving this pattern and why is it lasting so long?

First of all we are still in a pattern that favors blocking.  In the below graphs, note the AO and NAO and how they take another dive as we hit May.




As you can see, this means more strong cold fronts with 2-3 day warm up's ahead of each system and 2-3 days of a cool down behind each system.  Wash, rinse, and repeat.   The latest computer models indicate another trough coming in for next week around mid week with an associated cold front due in on Wed.  We then, will see another system next weekend and there is more beyond that taking us into the first week of May. 

The pattern also looks to remain active.  Take a look at the 11-15 day 500 MB height anomaly map for the 11-15 day period.


As you can see, a ridge builds into the Rockies with a trough along the East Coast and over SE Canada.  There is a weakness in the atmosphere that places the Great Lakes and Ohio Valley regions right in the cross hairs for continues storm system with warm up's and cool down's continuing for the next few weeks. 

For comparison, here is the 6-10 day from the ECMWF model.


The Euro produces a much colder pattern with a positive PNA type of pattern with the ridge centered further west and the trough is centered right over the Ohio Valley.  This is a much colder outcome here with a strong North Atlantic ridge.  This is not a negative NAO by the way.  So there you have it! 

Thanks for reading and I appreciate your feedback!

Active Weather Times Ahead

Good afternoon folks!  The cold and dry weather pattern that we had last week is gone.  It has been replaced by a warmer and more active pattern more typical of Spring.  In addition to the storms this week across the Ohio Valley and Great Lakes regions, after we cool down a bit on Friday and this weekend, warm air will make a return for next week.  Both the GFS and ECMWF computer models indicate more storms will be in our future.  The GFS model tries to bring in the next cold front on Monday while the ECMWF does so by Tuesday.  Both models indicate an active second half of next week!

Do we have any cold spells for the second half of April?  We just might see one!  Check out the AO Forecast.

Ensemble Mean AO Outlooks

As you can see, it takes a dip and we get cooler (Friday and this weekend).  Then it rises for next week and takes another dip just after mid month.  I am watching that period, after mid month, to see if we get another cool down similar to the one coming later this week.  This is a classic spring time battle between the warm and cold so severe weather events will become more common for the rest of April and into May as well.

Check out the GFS Ensemble Mean for the 11-15 day period.  It also agrees with a cooler pattern developing after mid month.



Basically, what we can expect going forward is bouts of warmth and cold with an active weather pattern in between.  Severe weather will also become more of a threat as well.  Enjoy the nice weather if you're reading this from Cincinnati and enjoy the storm potential later on today if you live off to the North.
