Severe storms approaching

A strong line of cells is formulating along a line from Del Rio to just north of Austin. This cell line in the last hour has had massive expansion and explosive nature. This system is currently moving east or just north of east. The unstable air mass over the San Antonio region may also contribute to the expansion and intensity of this system. This system has the potential for large hail, strong ground to sky lightning, localized flooding and vertical wind gusts in excess of 60mph. The exact timing is hard to tell based on the front edges expansion. The line is moving relatively slowly so I would say 8pm for the intense cells. weather 5.28.2017

Significant hail cells forming along three lines

There are a few strong cells that are forming along three separate lines. The latter two appear they might stay north of San Antonio but they are noted as questions marks. The first line is developing south of 90 with some of the cells currently moving through southwest and southeast San Antonio. However, they should be watched accordingly as they may produce strong lightning, hail and gusty 5.23.2017

Weather intensifying quickly

There is currently an unstable air mass to the southwest that is approaching the San Antonio region. There is also a strong line of thunderstorms pushing northwest from the gulf and is approaching the I10 corridor. These two seem to be meeting in the middle which is in the neighborhood of San Antonio. The weather is going to get rough quick and we can expect strong thunderstorms, heavy downpours and potential for severe weather.  Although there may be some really strong storms, this system is not very organized other than the line that is pushing northwest out of the gulf. This line appears to be attached to the backside of the old front as it extends up through the Mississippi. The largest threat that I see is large quantities of rain with localized flooding and moderate flooding. The weather will continue to be monitored through this evening and into tomorrow. There is lots of rain in the forecast for the next 18-24Weather 5.21.2017.png hours.

Severe weather inbound

Yes, this May has had some really unpredictable weather. The last two systems really just completely lost to the San Antonio convective zone. The overcast weather today will reduce this black asphalt-induced convection that has been destroying the moisture entering the San Antonio region. However, this evenings weather is developing quickly and strongly along a line from just west of Abilene through Fort Stockton. The dry line is developing rather quickly towards the southwest. This line has the potential to produce 50 plus mile per hour strong vertical wind shear, large size hail, isolated tornadoes and strong ground to sky lightning. The system also has the potential to produce localized flooding and bad driving conditions. The approximate arrival of the system appears to be between 6am and 8am. The current vector suggests an arrival time of 7am. The system could still slow but the main point is to prepare and plan to have extra time for the commute in the morning. weather 5.17.2017

Significant hail cells west of San Antonio

There are two cells moving to the east very slowly. The anticipated arrival of the first cell which is in Hondo right now will be about 12:30 am. This cell has shown a couple of episodes of ice popping up in its central west end. Along with this cell there is another one that is presently in Del Rio moving right behind the first cell. This one has also shown some hail spots. Along with these cells, there is a developing line off of the previous cold front that dropped baseball size hail in Denver. This dryline is looking quite weak and the squall looks very weak. The anticipated arrival seems to be about 9 to 10 am which should help to inhibit is intensity as cold fronts do not like day light hours. This setup will coWeather 5.11.2017ntinue to be monitored.

Squall line starting to shape

Yes, there is a decent start to the formation of a squall line that is starting to take shape in northwest Texas off the main cold front line moving into the west Oklahoma region. The dryline portion still has not developed quite well although it is night time and night time is the right time for cold front development. A strong dip in the jet stream will allow for the system to approach San Antonio and gulf moisture should assist in the development of the dry line. The dry line should advance southwest along the line as cells move across it to the just north of east. The exact intensity and distance the squall line develops to the south and west of the current line is still questionable. A weak low boundary across the line should also assist in its development. It feels like the outskirts of the squall line will make San Antonio by about 5am or so based on current trajectory. This system poses risks of heavy localized flooding rains, strong wind gusts, strong sky to ground lightning and potential for large sized hail. 5.03.2017 weather

Severe weather is materializing

Right now, the squall line has taken a beating from the sun as cold fronts do not do well with daylight. Although this is true, we are starting to move into the summer style rain systems so there has been a lot of tropical moisture that has been fueling the line. Right now we have daylight starting to leave and this system should start to come together. Right now the line looks very weak considering the amount of organized red in it is minimal. However, much can happen now that the sun is starting to go down and it can develop quickly and efficiently with the amount of unstable moist rising air in front of the dry line right now. This system has the potential to produce severe thunderstorms, strong vertical wind shear, some small to medium size hail and localized and moderate flooding. Stay away from areas that flood if you are out tonight.Weather 4.10.2017-2
