Reading a Weather Map worksheet with a detailed U.S. weather map and educational questions.

Let’s go step by step using the weather map and its key.

Question 1: According to the weather map, what is the weather like in Massachusetts/Baytown?

Look at Massachusetts on the map — it’s labeled “Baytown” near Boston. There’s a blue line with triangles pointing toward it — that’s a cold front. Also, there are rain symbols (dots) over that area. The temperature shown is 50°F, and wind is from the northwest at 15 mph.

So, Baytown is experiencing cool temperatures, rain, and windy conditions due to a cold front moving through.

→ Answer: Rainy and cool, with winds from the northwest. A cold front is passing through.

Question 2: What will the weather be like over the next few days in Massachusetts/Baytown?

Cold fronts bring cooler air behind them. Since the cold front is moving southeast (triangles point that way), after it passes, Baytown will have:

- Cooler temperatures
- Clearing skies (less rain)
- Winds shifting to north or northwest
- Possibly sunny but chilly

→ Answer: After the cold front passes, expect cooler, drier, and clearer weather.

Question 3: What is the weather like currently in Houston/Texas?

Houston is marked with a sun symbol → sunny. Temperature is 84°F. Wind is light from the south at 5 mph. No fronts nearby.

→ Answer: Sunny and warm, 84°F, with light southerly winds.

Question 4: What will the weather be like over the next few days in Houston/Texas?

There’s a warm front (red line with semicircles) approaching from the southwest, heading toward Texas. Warm fronts bring gradual warming and often clouds/rain ahead of them.

Since the warm front is moving northeast, Houston will likely see:

- Increasing clouds
- Possible rain as the front approaches
- Then warmer, more humid weather after the front passes

→ Answer: Expect increasing clouds and possible rain soon, followed by warmer, more humid weather.

Question 5: Denver/Colorado is experiencing rain over the next few days. What type of air mass is most likely causing that weather?

Denver has rain and is under a low-pressure system (L). Low pressure usually means rising air → clouds and precipitation. Also, look at the wind direction — winds are coming from the west/southwest. That suggests moist air from the Pacific or Gulf is being lifted.

But since Denver is inland and high elevation, and there’s a low-pressure center nearby, the rain is likely caused by a maritime tropical (mT) air mass bringing moisture from the Gulf of Mexico, or possibly a continental polar (cP) air mass colliding with warmer air — but given the location and typical patterns, moisture-laden air from the south or east is lifting over the Rockies.

Actually, looking again — Denver is near a low-pressure center, and there’s a cold front to the east. So the rain is likely from lifted moist air associated with the low-pressure system, which draws in maritime tropical (mT) air from the Gulf.

→ Answer: Maritime Tropical (mT) air mass — brings warm, moist air that rises and causes rain when it meets cooler air or is forced up by terrain.

*(Note: Some might say “frontal lift” or “low-pressure system,” but the question asks for “air mass.” mT is correct for moist, rainy conditions in this region.)*

Question 6: Los Angeles/California is experiencing hot and dry weather. What type of air mass is most likely causing that weather?

LA has a sun symbol, 92°F, very dry. It’s under a high-pressure system (H). High pressure = sinking air = clear, dry, hot weather.

The air mass responsible for hot, dry weather in California is typically Continental Tropical (cT) — forms over deserts (like Southwest US/Mexico), very dry and hot.

Sometimes in summer, it can also be influenced by subtropical highs, but cT is the standard answer for hot/dry continental air.

→ Answer: Continental Tropical (cT) air mass — hot and dry, originating over desert regions.

Final Answer:

1. Rainy and cool, with winds from the northwest. A cold front is passing through.
2. After the cold front passes, expect cooler, drier, and clearer weather.
3. Sunny and warm, 84°F, with light southerly winds.
4. Expect increasing clouds and possible rain soon, followed by warmer, more humid weather.
5. Maritime Tropical (mT) air mass.
6. Continental Tropical (cT) air mass.
