Keep an umbrella handy the next few days as a strong storm system blanketing the Rockies with snow and rain picks up steam and heads our way. We'll see a one-two punch of rain beginning Tuesday as showers drift in from south to north. Tuesday's rain is due to the cold front that moved through Monday moving back north as a warm front. The showers will be fairly light with 1/2 inch amounts common.
Our Super Microcast computer model shows the second round as a line of stronger storms moving in from the west during the morning Wednesday through the afternoon. A snapshot of the model depicts the storms by 3 pm Wednesday:

These storms could produce isolated tornadoes as well as heavy downpours. By the time it's all said and done, we could see upwards of 1 to 3 inches of rain by Wednesday afternoon in and around metro Houston. Neighborhoods north of town (Conroe, Tomball, Waller and northward towards Huntsville) could see up to 4 inches of rain. This is enough to cause flooding.
