Your Sunday Forecast – Seasonal Temps – Slight Chance for Rain

Good morning and happy Sunday!  A little upper level disturbance over west Texas will help generate slight chances for rain today mainly across north central, west central, and northern Hill Country regions of the state today.  We already have a bit of rain activity on the radar west of Waco and over towards San Angelo.  This activity is nearly stationary and will likely die out a bit before regenerating as we get into the afternoon hours and peak daytime heating.  Overall rainfall amounts will be light and no severe weather is expected.  Below is an animated radar forecast through 11pm tonight.

Highs today will be seasonal and in the 90s across most of the state.  We may see a few 100 degree readings across the Rio Grande plains.  Cloud cover and the potential for showers across central and north central Texas will help keep highs in check.  Lows tonight will also be seasonal and in the 60s across the western half of the state with 70s expected across the eastern half.  Thankfully, we’re beginning to move into that time of the year when seeing 100s during the day and 80s during the night becomes less frequent.  By now, I think just about everyone is ready for the return of fall temps in the weeks ahead.

And because we can’t take our eyes off the tropics just yet…we have another Tropical Storm, “Fred”, which formed last night just southeast of the Cape Verde islands off the coast of Africa.  Fred is expected to reach hurricane strength within the next 24 hours and track generally northwest over the next few days.  As he’s many days and thousands of miles away from any potential threat to the US coast…if he even survives that long…there is no way to tell just yet if he will become a threat to the US or Texas coast.  At any rate…we’ll continue to keep an eye on things and keep you updated with the latest information.

Typical August Weather Today; Watching Tropical Storm #Erika

After three days of thunderstorms producing localized wind damage across parts of the state we’re going to see coverage die down today. Central, South-Central, and Southeast Texas still have a 10 to 20 percent chance of storms this afternoon. Compared to the 30 to 40 percent chances on Monday and Tuesday we’ll see less activity today. By tonight rain chances will be near zero across all of Texas.

Temperatures will climb into the 90s this afternoon with 100-101 degrees across the Permian Basin and Deep South Texas. Another decently cool night across Northeast Texas later on wiht low 60s. Mid to upper 60s across the Texas Panhandle and West Texas plus the Alpine Mountains. Everyone else will be in the mid 70s for overnight lows into Thursday morning.

Tropical Storm Erika remains relatively disorganized this morning east of the LEsser Antilles in the Atlantic. Several hurricane hunter flights have been keeping a close eye on the system. Wind shear and bouts of dry air are keeping the system from organizing. We do not anticipate much in the way of strengthening over the next two days as Erika continues to struggle for life. I would not be surprised to see the system succumb to wind shear and degenerate into a tropical wave.

However if Erika does survive the next two to three days (which is a 50/50 chance) then Southern Florida has a real threat of being impacted by the storm. As Erika moves north of the Dominican Republic this weekend conditions will become much more favorable for development. By Sunday Night the National Hurricane Center has Erika on miami’s doorstep as a hurricane. There remains considerable uncertainty with this storm or even if it will survive the next two days. Without a doubt though a lot of folks will be keeping a close eye on things. I recommend you do the same if you’re heading to southern Florida this weekend or early next week.

All Eyes on Tropical Storm Erika…

I’ve been saying most of the summer that it does not matter how many tropical systems we get this season because it only takes one storm. The National Hurricane Center is now forecasting Erika to be a hurricane in the Bahamas by late Saturday Night. There remains considerable uncertainty over the track and potential intensity of Erika. There are some weather models that weaken Erika and make it a relative non-issue. Other weather models make Erika a potent hurricane by the end of the weekend. The same weather models also diverge on the eventual track of Erika. At this time I do feel confident in saying this will not be a Texas threat. Most likely this system will not even get into the Gulf of Mexico. On the other side of the spectrum parts of Florida and folks in the Bahamas will need to watch this system carefully. The first hurricane hunter aircraft to investigate this system will arrive this afternoon to give us our first good look inside the storm. Forecasting tropical systems is nearly as difficult as forecasting winter weather in Texas – things change and can change fast. There is no need to go cancel vacations or anything like that yet. Even though this will not be a Texas threat we’ll be watching it closely and posting updates.

For storm information specific to your area, please monitor products

HAZARDS AFFECTING LAND
———————-
WIND: Tropical storm conditions are possible within the watch

Tropical Storm Erika is Born in the Central Atlantic

Tropical Storm Erika has formed about 955 miles east of the Leeward Islands in the Central Atlantic Ocean. This system is moving west quickly at 20 MPH and strengthening is anticipated over the coming days. The current forecast from the National Hurricane Center takes Erika towards Puerto Rico and north of the Dominican Republic by Friday. The long-range forecast has Erika approaching the Bahamas to near Cuba on Saturday as a strong tropical storm, just under hurricane strength. Conditions aren’t overly favorable for strengthening but we’ll have to keep a close eye on this system over the coming days. I’m not worried about a Texas impact at this time.

Continued risk for Flooding and Tornadoes Today

FWD

2015-06-17_6-21-24

* At 6:30 AM the area of low pressure associated with the remnants of Bill were located very near Waco. This storm system continues to trek to the north/northwest. We should see a slowing of movement and the low will be sitting on the D/FW Metroplex around noon. By 10 PM it should be very near Gainesville – so essentially it’ll slam on the breaks this afternoon.

* Moderate to heavy rain continues in the D/FW Metroplex this morning. We should see the rain tamper down from widespread coverage down to scattered (50% or so) by early afternoon. Localized flooding will be possible.

* Isolated tornadoes will be possible along and east of the low pressure system – so along/east of Interstate 35/35W. Any tornadoes that develop will likely be weak, short-lived, but could spin up very quickly.

* While we’ve been lucky with flash flooding so far in the sense we haven’t had much – remember most of the water that’s falling will runoff into area lakes and rivers. Those remain full from the May rain so we’ll see an increase in their levels – possibly back up to major flood stage in some circumstances.

* Rain chances will continue into Thursday for portions of North Texas, Northeast Texas, and East Texas. Localized pockets of flooding will be possible from that activity along with a continued threat of isolated tornadoes.

* The best way for you to keep up with conditions near you along with current weather warnings is by utilizing our free interactive weather adar located on our website at www.texasstormchasers.com/radar
